RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Support for block_cache num_shards and other config via option string. Summary: Problem: Option string accepts only cache_size as parameter for block_cache which is specified as "block_cache=1M". It doesn't accept other parameters like num_shards etc. Changes : 1) ParseBlockBasedTableOption in block_based_table_factory is edited to accept cache options in the format "block_cache=<cache_size>:<num_shard_bits>:<strict_capacity_limit>:<high_pri_pool_ratio>". Options other than cache_size are optional to maintain backward compatibility. The changes are valid for block_cache_compressed as well. For example, "block_cache=1M:6:true:0.5", "block_cache=1M:6:true", "block_cache=1M:6" and "block_cache=1M" are all valid option strings. 2) Corresponding unit tests are added.

Allow fractional bits/key in BloomFilterPolicy (#6092) Summary: There's no technological impediment to allowing the Bloom filter bits/key to be non-integer (fractional/decimal) values, and it provides finer control over the memory vs. accuracy trade-off. This is especially handy in using the format_version=5 Bloom filter in place of the old one, because bits_per_key=9.55 provides the same accuracy as the old bits_per_key=10. This change not only requires refining the logic for choosing the best num_probes for a given bits/key setting, it revealed a flaw in that logic. As bits/key gets higher, the best num_probes for a cache-local Bloom filter is closer to bpk / 2 than to bpk * 0.69, the best choice for a standard Bloom filter. For example, at 16 bits per key, the best num_probes is 9 (FP rate = 0.0843%) not 11 (FP rate = 0.0884%). This change fixes and refines that logic (for the format_version=5 Bloom filter only, just in case) based on empirical tests to find accuracy inflection points between each num_probes. Although bits_per_key is now specified as a double, the new Bloom filter converts/rounds this to "millibits / key" for predictable/precise internal computations. Just in case of unforeseen compatibility issues, we round to the nearest whole number bits / key for the legacy Bloom filter, so as not to unlock new behaviors for it.

Also for unit tests that use fixture class, `TEST` is replaced with `TEST_F` as required in gtest. There are several custom `main` functions in our existing tests. To make this transition easier, I modify all `main` functions to fallow gtest notation. But eventually we can remove them and use implementation of `main` that gtest provides. ```lang=bash % cat ~/transform #!/bin/sh files=$(git ls-files '*test\.cc') for file in $files do if grep -q "rocksdb::test::RunAllTests()" $file then if grep -Eq '^class \w+Test {' $file then perl -pi -e 's/^(class \w+Test) {/${1}: public testing::Test {/g' $file perl -pi -e 's/^(TEST)/${1}_F/g' $file fi perl -pi -e 's/(int main.*\{)/${1}::testing::InitGoogleTest(&argc, argv);/g' $file perl -pi -e 's/rocksdb::test::RunAllTests/RUN_ALL_TESTS/g' $file fi done % sh ~/transform % make format ``` Second iteration of this diff contains only scripted changes.

options.level_compaction_dynamic_level_bytes to allow RocksDB to pick size bases of levels dynamically. Summary: When having fixed max_bytes_for_level_base, the ratio of size of largest level and the second one can range from 0 to the multiplier. This makes LSM tree frequently irregular and unpredictable. It can also cause poor space amplification in some cases. In this improvement (proposed by Igor Kabiljo), we introduce a parameter option.level_compaction_use_dynamic_max_bytes. When turning it on, RocksDB is free to pick a level base in the range of (options.max_bytes_for_level_base/options.max_bytes_for_level_multiplier, options.max_bytes_for_level_base] so that real level ratios are close to options.max_bytes_for_level_multiplier.

Refactor trimming logic for immutable memtables (#5022) Summary: MyRocks currently sets `max_write_buffer_number_to_maintain` in order to maintain enough history for transaction conflict checking. The effectiveness of this approach depends on the size of memtables. When memtables are small, it may not keep enough history; when memtables are large, this may consume too much memory. We are proposing a new way to configure memtable list history: by limiting the memory usage of immutable memtables. The new option is `max_write_buffer_size_to_maintain` and it will take precedence over the old `max_write_buffer_number_to_maintain` if they are both set to non-zero values. The new option accounts for the total memory usage of flushed immutable memtables and mutable memtable. When the total usage exceeds the limit, RocksDB may start dropping immutable memtables (which is also called trimming history), starting from the oldest one. The semantics of the old option actually works both as an upper bound and lower bound. History trimming will start if number of immutable memtables exceeds the limit, but it will never go below (limit-1) due to history trimming. In order the mimic the behavior with the new option, history trimming will stop if dropping the next immutable memtable causes the total memory usage go below the size limit. For example, assuming the size limit is set to 64MB, and there are 3 immutable memtables with sizes of 20, 30, 30. Although the total memory usage is 80MB > 64MB, dropping the oldest memtable will reduce the memory usage to 60MB < 64MB, so in this case no memtable will be dropped.

When statistics is enabled, and both options `stats_persist_period_sec` and `persist_stats_to_disk` are set, RocksDB will periodically write stats to a built-in column family in the following form: key -> (timestamp in microseconds)#(stats name), value -> stats value.

ReadaheadRandomAccessFile -- userspace readahead Summary: ReadaheadRandomAccessFile acts as a transparent layer on top of RandomAccessFile. When a Read() request is issued, it issues a much bigger request to the OS and caches the result. When a new request comes in and we already have the data cached, it doesn't have to issue any requests to the OS. We add ReadaheadRandomAccessFile layer only when file is read during compactions. D45105 was incorrectly closed by Phabricator because I committed it to a separate branch (not master), so I'm resubmitting the diff.

Optionally wait on bytes_per_sync to smooth I/O (#5183) Summary: The existing implementation does not guarantee bytes reach disk every `bytes_per_sync` when writing SST files, or every `wal_bytes_per_sync` when writing WALs. This can cause confusing behavior for users who enable this feature to avoid large syncs during flush and compaction, but then end up hitting them anyways. My understanding of the existing behavior is we used `sync_file_range` with `SYNC_FILE_RANGE_WRITE` to submit ranges for async writeback, such that we could continue processing the next range of bytes while that I/O is happening. I believe we can preserve that benefit while also limiting how far the processing can get ahead of the I/O, which prevents huge syncs from happening when the file finishes. Consider this `sync_file_range` usage: `sync_file_range(fd_, 0, static_cast<off_t>(offset + nbytes), SYNC_FILE_RANGE_WAIT_BEFORE | SYNC_FILE_RANGE_WRITE)`. Expanding the range to start at 0 and adding the `SYNC_FILE_RANGE_WAIT_BEFORE` flag causes any pending writeback (like from a previous call to `sync_file_range`) to finish before it proceeds to submit the latest `nbytes` for writeback. The latest `nbytes` are still written back asynchronously, unless processing exceeds I/O speed, in which case the following `sync_file_range` will need to wait on it. There is a second change in this PR to use `fdatasync` when `sync_file_range` is unavailable (determined statically) or has some known problem with the underlying filesystem (determined dynamically). The above two changes only apply when the user enables a new option, `strict_bytes_per_sync`.

Remove the support of setting CompressionOptions.parallel_threads from string for now (#6782) Summary: The current way of implementing CompressionOptions.parallel_threads introduces a format change. We plan to change CompressionOptions's serailization format to a new JSON-like format, which would be another format change. We would like to consolidate the two format changes into one, rather than making some users to change twice. Hold CompressionOptions.parallel_threads from being supported by option string for now. Will add it back after the general CompressionOptions's format change. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6782 Test Plan: Run all existing tests.

Refactor trimming logic for immutable memtables (#5022) Summary: MyRocks currently sets `max_write_buffer_number_to_maintain` in order to maintain enough history for transaction conflict checking. The effectiveness of this approach depends on the size of memtables. When memtables are small, it may not keep enough history; when memtables are large, this may consume too much memory. We are proposing a new way to configure memtable list history: by limiting the memory usage of immutable memtables. The new option is `max_write_buffer_size_to_maintain` and it will take precedence over the old `max_write_buffer_number_to_maintain` if they are both set to non-zero values. The new option accounts for the total memory usage of flushed immutable memtables and mutable memtable. When the total usage exceeds the limit, RocksDB may start dropping immutable memtables (which is also called trimming history), starting from the oldest one. The semantics of the old option actually works both as an upper bound and lower bound. History trimming will start if number of immutable memtables exceeds the limit, but it will never go below (limit-1) due to history trimming. In order the mimic the behavior with the new option, history trimming will stop if dropping the next immutable memtable causes the total memory usage go below the size limit. For example, assuming the size limit is set to 64MB, and there are 3 immutable memtables with sizes of 20, 30, 30. Although the total memory usage is 80MB > 64MB, dropping the oldest memtable will reduce the memory usage to 60MB < 64MB, so in this case no memtable will be dropped.

options.level_compaction_dynamic_level_bytes to allow RocksDB to pick size bases of levels dynamically. Summary: When having fixed max_bytes_for_level_base, the ratio of size of largest level and the second one can range from 0 to the multiplier. This makes LSM tree frequently irregular and unpredictable. It can also cause poor space amplification in some cases. In this improvement (proposed by Igor Kabiljo), we introduce a parameter option.level_compaction_use_dynamic_max_bytes. When turning it on, RocksDB is free to pick a level base in the range of (options.max_bytes_for_level_base/options.max_bytes_for_level_multiplier, options.max_bytes_for_level_base] so that real level ratios are close to options.max_bytes_for_level_multiplier. Test Plan: New unit tests and pass tests suites including valgrind.

Add columnfamily option optimize_filters_for_hits to optimize for key hits only Summary: Summary: Added a new option to ColumnFamllyOptions - optimize_filters_for_hits. This option can be used in the case where most accesses to the store are key hits and we dont need to optimize performance for key misses. This is useful when you have a very large database and most of your lookups succeed. The option allows the store to not store and use filters in the last level (the largest level which contains data). These filters can take a large amount of space for large databases (in memory and on-disk). For the last level, these filters are only useful for key misses and not for key hits. If we are not optimizing for key misses, we can choose to not store these filters for that level. This option is only provided for BlockBasedTable. We skip the filters when we are compacting Test Plan: 1. Modified db_test toalso run tests with an additonal option (skip_filters_on_last_level) 2.

Two DBOptions are introduced: `stats_persist_period_sec` (default 10 minutes) controls the intervals between two snapshots are taken; `max_stats_history_count` (default 10) controls the max number of history snapshots to keep in memory. RocksDB will stop collecting stats snapshots if `stats_persist_period_sec` is set to 0.

Persistent Stats: persist stats history to disk (#5046) Summary: This PR continues the work in https://github.com/facebook/rocksdb/pull/4748 and https://github.com/facebook/rocksdb/pull/4535 by adding a new DBOption `persist_stats_to_disk` which instructs RocksDB to persist stats history to RocksDB itself. When statistics is enabled, and both options `stats_persist_period_sec` and `persist_stats_to_disk` are set, RocksDB will periodically write stats to a built-in column family in the following form: key -> (timestamp in microseconds)#(stats name), value -> stats value. The existing API `GetStatsHistory` will detect the current value of `persist_stats_to_disk` and either read from in-memory data structure or from the hidden column family on disk.

Optionally wait on bytes_per_sync to smooth I/O (#5183) Summary: The existing implementation does not guarantee bytes reach disk every `bytes_per_sync` when writing SST files, or every `wal_bytes_per_sync` when writing WALs. This can cause confusing behavior for users who enable this feature to avoid large syncs during flush and compaction, but then end up hitting them anyways. My understanding of the existing behavior is we used `sync_file_range` with `SYNC_FILE_RANGE_WRITE` to submit ranges for async writeback, such that we could continue processing the next range of bytes while that I/O is happening. I believe we can preserve that benefit while also limiting how far the processing can get ahead of the I/O, which prevents huge syncs from happening when the file finishes. Consider this `sync_file_range` usage: `sync_file_range(fd_, 0, static_cast<off_t>(offset + nbytes), SYNC_FILE_RANGE_WAIT_BEFORE | SYNC_FILE_RANGE_WRITE)`. Expanding the range to start at 0 and adding the `SYNC_FILE_RANGE_WAIT_BEFORE` flag causes any pending writeback (like from a previous call to `sync_file_range`) to finish before it proceeds to submit the latest `nbytes` for writeback. The latest `nbytes` are still written back asynchronously, unless processing exceeds I/O speed, in which case the following `sync_file_range` will need to wait on it. There is a second change in this PR to use `fdatasync` when `sync_file_range` is unavailable (determined statically) or has some known problem with the underlying filesystem (determined dynamically). The above two changes only apply when the user enables a new option, `strict_bytes_per_sync`.

Try loading the options now, and it fails: $ ./ldb --db=/tmp/test_db --try_load_options get a1 Failed: Invalid argument: Unrecognized option DBOptions:: abcd Passes with the new --ignore_unknown_options flag $ ./ldb --db=/tmp/test_db --try_load_options --ignore_unknown_options get a1 b1 Closes https://github.com/facebook/rocksdb/pull/2423 Differential Revision: D5212091 Pulled By: sagar0 fbshipit-source-id: 2ec17636feb47dc0351b53a77e5f15ef7cbf2ca7

The ObjectRegistry class replaces the Registrar and NewCustomObjects.… (#5293) Summary: The ObjectRegistry class replaces the Registrar and NewCustomObjects. Objects are registered with the registry by Type (the class must implement the static const char *Type() method). This change is necessary for a few reasons: - By having a class (rather than static template instances), the class can be passed between compilation units, meaning that objects could be registered and shared from a dynamic library with an executable. - By having a class with instances, different units could have different objects registered. This could be useful if, for example, one Option allowed for a dynamic library and one did not. When combined with some other PRs (being able to load shared libraries, a Configurable interface to configure objects to/from string), this code will allow objects in external shared libraries to be added to a RocksDB image at run-time, rather than requiring every new extension to be built into the main library and called explicitly by every program.

Add columnfamily option optimize_filters_for_hits to optimize for key hits only Summary: Summary: Added a new option to ColumnFamllyOptions - optimize_filters_for_hits. This option can be used in the case where most accesses to the store are key hits and we dont need to optimize performance for key misses. This is useful when you have a very large database and most of your lookups succeed. The option allows the store to not store and use filters in the last level (the largest level which contains data). These filters can take a large amount of space for large databases (in memory and on-disk). For the last level, these filters are only useful for key misses and not for key hits. If we are not optimizing for key misses, we can choose to not store these filters for that level. This option is only provided for BlockBasedTable. We skip the filters when we are compacting Test Plan: 1. Modified db_test toalso run tests with an additonal option (skip_filters_on_last_level) 2.

Allow fractional bits/key in BloomFilterPolicy (#6092) Summary: There's no technological impediment to allowing the Bloom filter bits/key to be non-integer (fractional/decimal) values, and it provides finer control over the memory vs. accuracy trade-off. This is especially handy in using the format_version=5 Bloom filter in place of the old one, because bits_per_key=9.55 provides the same accuracy as the old bits_per_key=10. This change not only requires refining the logic for choosing the best num_probes for a given bits/key setting, it revealed a flaw in that logic. As bits/key gets higher, the best num_probes for a cache-local Bloom filter is closer to bpk / 2 than to bpk * 0.69, the best choice for a standard Bloom filter. For example, at 16 bits per key, the best num_probes is 9 (FP rate = 0.0843%) not 11 (FP rate = 0.0884%). This change fixes and refines that logic (for the format_version=5 Bloom filter only, just in case) based on empirical tests to find accuracy inflection points between each num_probes. Although bits_per_key is now specified as a double, the new Bloom filter converts/rounds this to "millibits / key" for predictable/precise internal computations. Just in case of unforeseen compatibility issues, we round to the nearest whole number bits / key for the legacy Bloom filter, so as not to unlock new behaviors for it.

Support for block_cache num_shards and other config via option string. Summary: Problem: Option string accepts only cache_size as parameter for block_cache which is specified as "block_cache=1M". It doesn't accept other parameters like num_shards etc. Changes : 1) ParseBlockBasedTableOption in block_based_table_factory is edited to accept cache options in the format "block_cache=<cache_size>:<num_shard_bits>:<strict_capacity_limit>:<high_pri_pool_ratio>". Options other than cache_size are optional to maintain backward compatibility. The changes are valid for block_cache_compressed as well. For example, "block_cache=1M:6:true:0.5", "block_cache=1M:6:true", "block_cache=1M:6" and "block_cache=1M" are all valid option strings. 2) Corresponding unit tests are added.

Option string/map/file can set env from object registry (#5237) Summary: - By providing the "env" field in any text-based options (i.e., string, map, or file), we can use `NewCustomObject` to deserialize the text value into an actual `Env` object. - Currently factory functions for `Env` registered with object registry should only return pointer to static `Env` objects. That's because `DBOptions::env` is a raw pointer so we cannot easily delegate cleanup. - Note I did not add `env` to `db_option_type_info`. It wasn't needed for (de)serialization, and I believe we don't want to do verification on `env`, even by checking name. That's because the user should be able to copy their DB from Linux to Windows, change envs, and not see an option verification error.

The ObjectRegistry class replaces the Registrar and NewCustomObjects.… (#5293) Summary: The ObjectRegistry class replaces the Registrar and NewCustomObjects. Objects are registered with the registry by Type (the class must implement the static const char *Type() method). This change is necessary for a few reasons: - By having a class (rather than static template instances), the class can be passed between compilation units, meaning that objects could be registered and shared from a dynamic library with an executable. - By having a class with instances, different units could have different objects registered. This could be useful if, for example, one Option allowed for a dynamic library and one did not. When combined with some other PRs (being able to load shared libraries, a Configurable interface to configure objects to/from string), this code will allow objects in external shared libraries to be added to a RocksDB image at run-time, rather than requiring every new extension to be built into the main library and called explicitly by every program.

The ObjectRegistry class replaces the Registrar and NewCustomObjects.… (#5293) Summary: The ObjectRegistry class replaces the Registrar and NewCustomObjects. Objects are registered with the registry by Type (the class must implement the static const char *Type() method). This change is necessary for a few reasons: - By having a class (rather than static template instances), the class can be passed between compilation units, meaning that objects could be registered and shared from a dynamic library with an executable. - By having a class with instances, different units could have different objects registered. This could be useful if, for example, one Option allowed for a dynamic library and one did not. When combined with some other PRs (being able to load shared libraries, a Configurable interface to configure objects to/from string), this code will allow objects in external shared libraries to be added to a RocksDB image at run-time, rather than requiring every new extension to be built into the main library and called explicitly by every program. Test plan (on riversand963's devserver) ``` $COMPILE_WITH_ASAN=1 make -j32 all && sleep 1 && make check ``` All tests pass.

An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Introduce a new storage specific Env API (#5761) Summary: The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc. This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO. The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before. This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection. The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Introduce a new storage specific Env API (#5761) Summary: The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc. This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO. The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before. This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection.

RocksDBOptionsParser::Parse()'s `ignore_unknown_options` argument only ingores options from higher version. Summary: RocksDB should always be able to parse an option file generated using the same or lower version. Unknown option should only happen if it is from a higher version. Change the behavior of RocksDBOptionsParser::Parse()'s behavior with ignore_unknown_options=true so that unknown option from a lower or the same version will never be skipped.

Introduce a new storage specific Env API (#5761) Summary: The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc. This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO. The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before. This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection. The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

Allow ignoring unknown options when loading options from a file Summary: Added a flag, `ignore_unknown_options`, to skip unknown options when loading an options file (using `LoadLatestOptions`/`LoadOptionsFromFile`) or while verifying options (using `CheckOptionsCompatibility`). This will help in downgrading the db to an older version. Also added `--ignore_unknown_options` flag to ldb **Example Use case:** In MyRocks, if copying from newer version to older version, it is often impossible to start because of new RocksDB options that don't exist in older version, even though data format is compatible. MyRocks uses these load and verify functions in [ha_rocksdb.cc::check_rocksdb_options_compatibility](https://github.com/facebook/mysql-5.6/blob/e004fd9f416821d043ccc8ad4a345c33ac9953f0/storage/rocksdb/ha_rocksdb.cc#L3348-L3401). **Test Plan:** Updated the unit tests. `make check` ldb: $ ./ldb --db=/tmp/test_db --create_if_missing put a1 b1 OK Now edit /tmp/test_db/<OPTIONS-file> and add an unknown option. Try loading the options now, and it fails: $ ./ldb --db=/tmp/test_db --try_load_options get a1 Failed: Invalid argument: Unrecognized option DBOptions:: abcd Passes with the new --ignore_unknown_options flag $ ./ldb --db=/tmp/test_db --try_load_options --ignore_unknown_options get a1 b1 Closes https://github.com/facebook/rocksdb/pull/2423 Differential Revision: D5212091 Pulled By: sagar0 fbshipit-source-id: 2ec17636feb47dc0351b53a77e5f15ef7cbf2ca7

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Replace dynamic_cast<> Summary: Replace dynamic_cast<> so that users can choose to build with RTTI off, so that they can save several bytes per object, and get tiny more memory available. Some nontrivial changes: 1. Add Comparator::GetRootComparator() to get around the internal comparator hack 2. Add the two experiemental functions to DB 3. Add TableFactory::GetOptionString() to avoid unnecessary casting to get the option string 4. Since 3 is done, move the parsing option functions for table factory to table factory files too, to be symmetric.

Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Introduce a new storage specific Env API (#5761) Summary: The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc. This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO. The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before. This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection. The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Introduce a new storage specific Env API (#5761) Summary: The current Env API encompasses both storage/file operations, as well as OS related operations. Most of the APIs return a Status, which does not have enough metadata about an error, such as whether its retry-able or not, scope (i.e fault domain) of the error etc., that may be required in order to properly handle a storage error. The file APIs also do not provide enough control over the IO SLA, such as timeout, prioritization, hinting about placement and redundancy etc. This PR separates out the file/storage APIs from Env into a new FileSystem class. The APIs are updated to return an IOStatus with metadata about the error, as well as to take an IOOptions structure as input in order to allow more control over the IO. The user can set both ```options.env``` and ```options.file_system``` to specify that RocksDB should use the former for OS related operations and the latter for storage operations. Internally, a ```CompositeEnvWrapper``` has been introduced that inherits from ```Env``` and redirects individual methods to either an ```Env``` implementation or the ```FileSystem``` as appropriate. When options are sanitized during ```DB::Open```, ```options.env``` is replaced with a newly allocated ```CompositeEnvWrapper``` instance if both env and file_system have been specified. This way, the rest of the RocksDB code can continue to function as before. This PR also ports PosixEnv to the new API by splitting it into two - PosixEnv and PosixFileSystem. PosixEnv is defined as a sub-class of CompositeEnvWrapper, and threading/time functions are overridden with Posix specific implementations in order to avoid an extra level of indirection. The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

The ```CompositeEnvWrapper``` translates ```IOStatus``` return code to ```Status```, and sets the severity to ```kSoftError``` if the io_status is retryable. The error handling code in RocksDB can then recover the DB automatically.

Allow upgrades from nullptr to some merge operator Summary: Currently, RocksDB does not allow reopening a preexisting DB with no merge operator defined, with a merge operator defined. This means that if a DB ever want to add a merge operator, there's no way to do so currently. Fix this by adding a new verification type `kByNameAllowFromNull` which will allow old values to be nullptr, and new values to be non-nullptr.

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059

Add Functions to OptionTypeInfo (#6422) Summary: Added functions for parsing, serializing, and comparing elements to OptionTypeInfo. These functions allow all of the special cases that could not be handled directly in the map of OptionTypeInfo to be moved into the map. Using these functions, every type can be handled via the map rather than special cased. By adding these functions, the code for handling options can become more standardized (fewer special cases) and (eventually) handled completely by common classes.

Add OptionTypeInfo::Enum and related methods (#6423) Summary: Add methods and constructors for handling enums to the OptionTypeInfo.

Add OptionTypeInfo::Enum and related methods (#6423) Summary: Add methods and constructors for handling enums to the OptionTypeInfo. This change allows enums to be converted/compared without adding a special "type" to the OptionType. This change addresses a couple of issues: - It allows new enumerated types to be added to the options without editing the OptionType base class (and related methods) - It standardizes the procedure for adding enumerated types to the options, reducing potential mistakes - It moves the enum maps to the location where they are used, allowing them to be static file members rather than global values - It reduces the number of types and cases that need to be handled in the various OptionType methods Pull Request resolved: https://github.com/facebook/rocksdb/pull/6423 Reviewed By: siying Differential Revision: D21408713 Pulled By: zhichao-cao fbshipit-source-id: fc492af285d011822578b95d186a0fce25d35626

RocksDB Options file format and its serialization / deserialization. Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059
