Support building db_bench using buck (#13004)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/13004 The patch extends the buckifier script so it generates a target for `db_bench` as well. Reviewed By: cbi42 Differential Revision: D62407071 fbshipit-source-id: 0cb98a324ce0598ad84a8675aa77b7d0f91bf40c |

Provide a way to invoke a callback for a Cache handle (#12987)
Summary: Add the `ApplyToHandle` method to the `Cache` interface to allow a caller to request the invocation of a callback on the given cache handle. The goal here is to allow a cache that manages multiple cache instances to use a callback on a handle to determine which instance it belongs to. For example, the callback can hash the key and use that to pick the correct target instance. This is useful to redirect methods like `Ref` and `Release`, which don't know the cache key.

Add documentation for background job's state transition (#12994)
Summary: The `SchedulePending*` API is a bit confusing since it doesn't immediately schedule the work and can be confused with the actual scheduling. So I have changed these to be `EnqueuePending*` and added some documentation for the corresponding state transitions of these background work.

Disable WAL fault injection in some case (#13000)
Summary: when manual_wal_flush is true and when there are more than 1 CF, WAL fault injection can cause CFs to be inconsistent. See more explanation and repro in T199157789. Disable the combination for now until we have a fix that allows auto recovery. This also helps to see if there's other cause of stress test failures. Pull Request resolved: https://github.com/facebook/rocksdb/pull/13000 Test Plan: the following command could repro db consistency failure in a few runs before this PR. From stress test output we can also see that exclude_wal_from_write_fault_injection and metadata_write_fault_one_in are sanitized to 0. ``` python3 ./tools/db_crashtest.py blackbox --interval=60

Fix and clarify ignore_unknown_options (#12989)
Summary: `ignore_unknown_options=true` had an undocumented behavior of having no effect (disallow unknown options) if reading from the same or older major.minor version. Presumably this was intended to catch unintentional addition of new options in a patch release, but there is no automated version compatibility testing between patch releases. So this was a bad choice without such testing support, because it just means users would hit the failure in case of adding features to a patch release. In this diff we respect ignore_unknown_options when reading a file from any newer version, even patch versions, and document this behavior in the API. I don't think it's practical or necessary to test among patch releases in check_format_compatible.sh. This seems like an exceptional case of applying a *different semantics* to patch version updates than to minor/major versions.

Add a new file ingestion option `link_files` (#12980)
Summary: Add option `IngestExternalFileOptions::link_files` that hard links input files and preserves original file links after ingestion, unlike `move_files` which will unlink input files after ingestion. This can be useful when being used together with `allow_db_generated_files` to ingest files from another DB. Also reverted the change to `move_files` in https://github.com/facebook/rocksdb/issues/12959 to simplify the contract so that it will always unlink input files without exception. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12980 Test Plan: updated unit test `ExternSSTFileLinkFailFallbackTest.LinkFailFallBackExternalSst` to test that input files will not be unlinked.

Summary: so `IngestExternalFileOptions::move_files` and `IngestExternalFileOptions::allow_db_generated_files` are now compatible. The original file links won't be removed if `allow_db_generated_files` is true. This is to prevent deleting files from another DB.

Enable Continuous Benchmarking of RocksDB (#12885)
Summary: This pull request transitions the benchmarking process from CircleCI to GitHub Actions. The benchmarking jobs will now be executed on a self-hosted runner. Unlike the previous CircleCI configuration, where jobs were queued due to the long execution time (nearly 60 minutes per job), the new setup schedules the benchmarking tasks to run every two hours.

Add an option to verify memtable key order during reads (#12889)
Summary: add a new CF option `paranoid_memory_checks` that allows additional data integrity validations during read/scan. Currently, skiplist-based memtable will validate the order of keys visited. Further data validation can be added in different layers. The option will be opt-in due to performance overhead. The motivation for this feature is for services where data correctness is critical and want to detect in-memory corruption earlier. For a corrupted memtable key, this feature can help to detect it during during reads instead of during flush with existing protections (OutputValidator that verifies key order or per kv checksum). See internally linked task for more context. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12889 Test Plan: * new unit test added for paranoid_memory_checks=true. * existing unit test for paranoid_memory_checks=false. * enable in stress test.

Best efforts recovery recover seqno prefix (#12938)
Summary: This PR make best efforts recovery more permissive by allowing it to recover incomplete Version that presents a valid point in time view from the user's perspective. Currently, a Version is only valid and saved if all files consisting that Version can be found. With this change, if only a suffix of L0 files (and their associated blob files) are missing, a valid Version is also available to be saved and recover to. Note that we don't do this if the column family was atomically flushed. Because atomic flush also need a consistent view across the column families, we cannot guarantee that if we are recovering to incomplete version.

Option to decouple index and filter partitions (#12939)
Summary: Partitioned metadata blocks were introduced back in 2017 to deal more gracefully with large DBs where RAM is relatively scarce and some data might be much colder than other data. The feature allows metadata blocks to compete for memory in the block cache against data blocks while alleviating tail latencies and thrash conditions that can arise with large metadata blocks (sometimes megabytes each) that can arise with large SST files. In general, the cost to partitioned metadata is more CPU in accesses (especially for filters where more binary search is needed before hashing can be used) and a bit more memory fragmentation and related overheads. However the feature has always had a subtle limitation with a subtle effect on performance: index partitions and filter partitions must be cut at the same time, regardless of which wins the space race (hahaha) to metadata_block_size. Commonly filters will be a few times larger than indexes, so index partitions will be under-sized compared to filter (and data) blocks. While this does affect fragmentation and related overheads a bit, I suspect the bigger impact on performance is in the block cache. The coupling of the partition cuts would be defensible if the binary search done to find the filter block was used (on filter hit) to short-circuit binary search to an index partition, but that optimization has not been developed. Consider two metadata blocks, an under-sized one and a normal-sized one, covering proportional sections of the key space with the same density of read queries. The under-sized one will be more prone to eviction from block cache because it is used less often. This is unfair because of its despite its proportionally smaller cost of keeping in block cache, and most of the cost of a miss to re-load it (random IO) is not proportional to the size (similar latency etc. up to ~32KB). ## This change Adds a new table option decouple_partitioned_filters allows filter blocks and index blocks to be cut independently. To make this work, the partitioned filter block builder needs to know about the previous key, to generate an appropriate separator for the partition index. In most cases, BlockBasedTableBuilder already has easy access to the previous key to provide to the filter block builder. This change includes refactoring to pass that previous key to the filter builder when available, with the filter building caching the previous key itself when unavailable, such as during compression dictionary training and some unit tests. Access to the previous key eliminates the need to track the previous prefix, which results in a small SST construction CPU win in prefix filtering cases, regardless of coupling, and possibly a small regression for some non-prefix cases, regardless of coupling, but still overall improvement especially with https://github.com/facebook/rocksdb/issues/12931. Suggested follow-up: * Update confusing use of "last key" to refer to "previous key" * Expand unit test coverage with parallel compression and dictionary training * Consider an option or enhancement to alleviate under-sized metadata blocks "at the end" of an SST file due to no coordination or awareness of when files are cut. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12939 Test Plan: unit tests updated. Also did some unit test runs with "hard wired" usage of parallel compression and dictionary training code paths to ensure they were working. Also ran blackbox_crash_test for a while with the new feature. ## SST write performance (CPU) Using the same testing setup as in https://github.com/facebook/rocksdb/issues/12931 but with -decouple_partitioned_filters=1 in the "after" configuration, which benchmarking shows makes almost no difference in terms of SST write CPU. "After" vs. "before" this PR ``` -partition_index_and_filters=0 -prefix_size=0 -whole_key_filtering=1 923691 vs. 924851 (-0.13%) -partition_index_and_filters=0 -prefix_size=8 -whole_key_filtering=0 921398 vs. 922973 (-0.17%) -partition_index_and_filters=0 -prefix_size=8 -whole_key_filtering=1 902259 vs. 908756 (-0.71%) -partition_index_and_filters=1 -prefix_size=8 -whole_key_filtering=0 917932 vs. 916901 (+0.60%) -partition_index_and_filters=1 -prefix_size=8 -whole_key_filtering=0 912755 vs. 907298 (+0.60%) -partition_index_and_filters=1 -prefix_size=8 -whole_key_filtering=1 899754 vs. 892433 (+0.82%) ``` I think this is a pretty good trade, especially in attracting more movement toward partitioned configurations. ## Read performance Let's see how decoupling affects read performance across various degrees of memory constraint. To simplify LSM structure, we're using FIFO compaction. Since decoupling will overall increase metadata block size, we control for this somewhat with an extra "before" configuration with larger metadata block size setting (8k instead of 4k). Basic setup: ``` (for CS in 0300 1200; do TEST_TMPDIR=/dev/shm/rocksdb1 ./db_bench -benchmarks=fillrandom,flush,readrandom,block_cache_entry_stats -num=5000000 -duration=30 -disable_wal=1 -write_buffer_size=30000000 -bloom_bits=10 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -partition_index_and_filters=1 -statistics=1 -cache_size=${CS}000000 -metadata_block_size=4096 -decouple_partitioned_filters=1 2>&1 | tee results-$CS; done) ``` And read ops/s results: ```CSV Cache size MB,After/decoupled/4k,Before/4k,Before/8k 3,15593,15158,12826 6,16295,16693,14134 10,20427,20813,18459 20,27035,26836,27384 30,33250,31810,33846 60,35518,32585,35329 100,36612,31805,35292 300,35780,31492,35481 1000,34145,31551,35411 1100,35219,31380,34302 1200,35060,31037,34322 ``` If you graph this with log scale on the X axis (internal link: https://pxl.cl/5qKRc), you see that the decoupled/4k configuration is essentially the best of both the before/4k and before/8k configurations: handles really tight memory closer to the old 4k configuration and handles generous memory closer to the old 8k configuration.

Do not add unprep_seqs when WriteImpl() fails in unprepared txn (#12927)
Summary: With the following scenario, we see assertion failure in write_unprepared_txn 1. The write is the first one in the transaction (`log_number_` is not set yet - https://github.com/facebook/rocksdb/blob/main/utilities/transactions/write_unprepared_txn.cc#L376-L379) 2. `WriteToWAL()` fails inside `db_impl_->WriteImpl()` due to fault injection. `last_log_number_`is 0. https://github.com/facebook/rocksdb/blob/main/utilities/transactions/write_unprepared_txn.cc#L386 3. `prepare_batch_cnt_` is still added to `unprep_seqs_` https://github.com/facebook/rocksdb/blob/main/utilities/transactions/write_unprepared_txn.cc#L395-L398 4. When the transaction gets destructed after failed, it expects `log_number_ > 0` if `unprep_seqs_` is not empty - https://github.com/facebook/rocksdb/blob/main/utilities/transactions/write_unprepared_txn.cc#L54-L55. Step 3 is wrong. `unprep_seqs_` is for the ordered list of unprep sequence numbers that we have already written to the DB. If `db_impl_->WriteImpl()` failed, `unprep_seqs_` shouldn't be set. `prepare_seq` value would be wrong anyway.

Optimize, simplify filter block building (fix regression) (#12931)
Summary:
This is in part a refactoring / simplification to set up for "decoupled" partitioned filters and in part to fix an intentional regression for a correctness fix in https://github.com/facebook/rocksdb/issues/12872. Basically, we are taking out some complexity of the filter block builders, and pushing part of it (simultaneous de-duplication of prefixes and whole keys) into the filter bits builders, where it is more efficient by operating on hashes (rather than copied keys).
Previously, the FullFilterBlockBuilder had a somewhat fragile and confusing set of conditions under which it would keep a copy of the most recent prefix and most recent whole key, along with some other state that is essentially redundant. Now we just track (always) the previous prefix in the PartitionedFilterBlockBuilder, to deal with the boundary prefix Seek filtering problem. (Btw, the next PR will optimize this away since BlockBasedTableReader already tracks the previous key.) And to deal with the problem of de-duplicating both whole keys and prefixes going into a single filter, we add a new function to FilterBitsBuilder that has that extra de-duplication capabilty, which is relatively efficient because we only have to cache an extra 64-bit hash, not a copied key or prefix. (The API of this new function is somewhat awkward to avoid a small CPU regression in some cases.)
Also previously, there was awkward logic split between FullFilterBlockBuilder and PartitionedFilterBlockBuilder to deal with some things specific to partitioning. And confusing names like Add vs. AddKey. FullFilterBlockBuilder is much cleaner and simplified now.
The splitting of PartitionedFilterBlockBuilder::MaybeCutAFilterBlock into DecideCutAFilterBlock and CutAFilterBlock is to address what would have been a slight performance regression in some cases. The split allows for more intruction-level parallelism by reducing unnecessary control dependencies.

Move file tracking in VersionEditHandlerPointInTime to VersionBuilder (#12928)
Summary: `VersionEditHandlerPointInTime` is tracking found files, missing files, intermediate files in order to decide to build a `Version` on negative edge trigger (transition from valid to invalid) without applying the current `VersionEdit`. However, applying `VersionEdit` and check completeness of a `Version` are specialization of `VersionBuilder`. More importantly, when we augment best efforts recovery to recover not just complete point in time Version but also a prefix of seqno for a point in time Version, such checks need to be duplicated in `VersionEditHandlerPointInTime` and `VersionBuilder`. To avoid this, this refactor move all the file tracking functionality in `VersionEditHandlerPointInTime` into `VersionBuilder`. To continue to let `VersionEditHandlerPIT` do the edge trigger check and build a `Version` before applying the current `VersionEdit`, a suite of APIs to supporting creating a save point and its associated functions are added in `VersionBuilder` to achieve this.

Disable WAL recycling in crash test; reproducer for recovery data loss (#12918)
Summary: I was investigating a crash test failure with "Corruption: SST file is ahead of WALs" which I haven't reproduced, but I did reproduce a data loss issue on recovery which I suspect could be the same root problem. The problem is already somewhat known (see https://github.com/facebook/rocksdb/issues/12403 and https://github.com/facebook/rocksdb/issues/12639) where it's only safe to recovery multiple recycled WAL files with trailing old data if the sequence numbers between them are adjacent (to ensure we didn't lose anything in the corrupt/obsolete WAL tail). However, aside from disableWAL=true, there are features like external file ingestion that can increment the sequence numbers without writing to the WAL. It is simply unsustainable to worry about this kind of feature interaction limiting where we can consume sequence numbers. It is very hard to test and audit as well. For reliable crash recovery of recycled WALs, we need a better way of detecting that we didn't drop data from one WAL to the next. Until then, let's disable WAL recycling in the crash test, to help stabilize it. Ideas for follow-up to fix the underlying problem: (a) With recycling, we could always sync the WAL before opening the next one. HOWEVER, this potentially very large sync could cause a big hiccup in writes (vs. O(1) sized manifest sync). (a1) The WAL sync could ensure it is truncated to size, or (a2) By requiring track_and_verify_wals_in_manifest, we could assume that the last synced size in the manifest is the final usable size of the WAL. (It might also be worth avoiding truncating recycled WALs.) (b) Add a new mechanism to record and verify the final size of a WAL without requiring a sync. (b1) By requiring track_and_verify_wals_in_manifest, this could be new WAL metadata recorded in the manifest (at the time of switching WALs). Note that new fields of WalMetadata are not forward-compatible, but a new kind of manifest record (next to WalAddition, WalDeletion; e.g. WalCompletion) is IIRC forward-compatible. (b2) A new kind of WAL header entry (not forward compatible, unfortunately) could record the final size of the previous WAL.

Fix CreateCheckpoint not handling failed CleanStagingDirectory well (#12894)
Summary: **Context/Summary:** `CleanStagingDirectory()` is called when the temporary .tmp folder we use to create checkpoint is not empty to begin with. Expanded fault injection can make this call fail e.g, `Delete file /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/.checkpoint17.tmp/012393.sst -- IO error: injected metadata write error`. But The result of `CleanStagingDirectory()` is ignored in `CreateCheckpoint()`. So the injected IO error can't be propagated to db stress test and handled correctly. Hence we see `While mkdir: /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/.checkpoint17.tmp: File exists` when we try to re-use a non-empty .tmp folder for new snapshots.

Fix file deletions in DestroyDB not rate limited (#12891)
Summary: Make `DestroyDB` slowly delete files if it's configured and enabled via `SstFileManager`. It's currently not available mainly because of DeleteScheduler's logic related to tracked total_size_ and total_trash_size_. These accounting and logic should not be applied to `DestroyDB`. This PR adds a `DeleteUnaccountedDBFile` util for this purpose which deletes files without accounting it. This util also supports assigning a file to a specified trash bucket so that user can later wait for a specific trash bucket to be empty. For `DestroyDB`, files with more than 1 hard links will be deleted immediately. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12891 Test Plan: Added unit tests, existing tests.

Fix filter partition size logic (#12904)
Summary: Was checking == a desired number of entries added to a filter, when the combination of whole key and prefix filtering could add more than one entry per table internal key. This could lead to unnecessarily large filter partitions, which could affect performance and block cache fairness. Also (only somewhat related because of other work in progress): * Some variable renaming and a new assertion in BlockBasedTableBuilder, to add some clarity. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12904 Test Plan: If you add assertion logic to the base revision checking that the partition cut is requested whenever `keys_added_to_partition_ >= keys_per_partition_`, it fails on a number of db_bloom_filter_test tests. However, such an assertion in the revised code would be essentially redundant with the new logic. If I added a regression test for this, it would be tricky and fragile, so I don't think it's important enough to chase and maintain. (Open to suggestions / input.)
