Allow disableWAL+recycle with WritePreparedTxnDB internals (#12639)
Summary: Follow-up from https://github.com/facebook/rocksdb/issues/12403 The crash test was periodically failing with the "disableWAL option is not supported if recycle_log_file_num > 0" failure, despite not setting the disableWAL from the user side. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12639 Test Plan: db_stress reproducer now passes. Added WAL recycling to txn DB unit tests, which is generally more difficult for correctness. Many tests now cover this change and pass.

Support MultiGetEntity in optimistic and WriteCommitted pessimistic transactions (#12634)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12634 The patch implements support for the `MultiGetEntity` API in optimistic transactions and pessimistic transactions with the WriteCommitted policy. Similarly to the other wide-column transaction APIs, the implementation leverages the `WriteBatchWithIndex` layer.

Improve the sanity checks in (Multi)GetEntity and friends (#12630)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12630 The patch cleans up, improves, and brings into sync (to the extent possible without API signature changes) the sanity checks around the `GetEntity` / `MultiGetEntity` family of APIs, including the read-your-own-writes (`WriteBatchWithIndex`) and transaction layers. The checks are centralized in two main sets of entry points, namely in `DB(Impl)` and the "main" `GetEntityFromBatchAndDB` / `MultiGetEntityFromBatchAndDB` overloads in `WriteBatchWithIndex`. This eliminates the need to duplicate the checks in the transaction classes. Reviewed By: jaykorean Differential Revision: D57125741 fbshipit-source-id: 4dd059ef644a9b173fbba767538943397e4cc6cd |

Add PutEntity support for optimistic and WritePrepared pessimistic transactions (#12606)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12606 The patch extends optimistic transactions and WriteCommitted pessimistic transactions with support for the `PutEntity` API. Similarly to the other APIs, `PutEntity` is available via both the `Transaction` and `TransactionDB` interfaces, where using the latter executes the write in a single-operation transaction as usual. Support for read APIs and other write policies (WritePrepared, WriteUnprepared) will be added in separate PRs.

Sync non-latest WALs during flush for 2PC, single-CF DBs (#12622)
Summary: Previously we skipped syncing the non-latest WALs during memtable flush when the DB had only one column family. Normally that is fine because those non-latest WALs would not be read by recovery. However, in case of `DBOptions::allow_2pc == true`, there could be unmatched prepare records in those WALs making them needed by recovery. As a result, the missing sync could have resulted in the recovered WAL state falling behind the recovered SST state. When we detect that case, we return a `Status::Corruption` saying "SST file is ahead of WALs". This PR proposes syncing the WAL in case of `DBOptions::allow_2pc`. This introduces the sync in some scenarios where it isn't needed (e.g., non-recent WALs contain no prepares) but I suspect the simplicity is worth it.

Retry DB::Open upon a corruption detected while reading the MANIFEST (#12518)
Summary: This PR is a counterpart of https://github.com/facebook/rocksdb/issues/12427 . On file systems that support storage level data checksum and reconstruction, retry opening the DB if a corruption is detected when reading the MANIFEST. This could be done in `log::Reader`, but its a little complicated since the sequential file would have to be reopened in order to re-read the same data, and we may miss some subtle corruptions that don't result in checksum mismatch. The approach chosen here instead is to make the decision to retry in `DBImpl::Recover`, based on either an explicit corruption in the MANIFEST file, or missing SST files due to bad data in the MANIFEST.

JNI get_helper code sharing / multiGet() use efficient batch C++ support (#12344)
Summary: Implement RAII-based helpers for JNIGet() and multiGet() Replace JNI C++ helpers `rocksdb_get_helper, rocksdb_get_helper_direct`, `multi_get_helper`, `multi_get_helper_direct`, `multi_get_helper_release_keys`, `txn_get_helper`, and `txn_multi_get_helper`. The model is to entirely do away with a single helper, instead a number of utility methods allow each separate JNI `Get()` and `MultiGet()` method to organise their parameters efficiently, then call the underlying C++ `db->Get()`, `db->MultiGet()`, `txn->Get()`, or `txn->MultiGet()` method itself, and use further utilities to retrieve results. Roughly speaking: * get keys into C++ form * Call C++ Get() * get results and status into Java form We achieve a useful performance gain as part of this work; by using the updated C++ multiGet we immediately pick up its performance gains (batch improvements to multiGet C++ were previously implemented, but not until now used by Java/JNI). multiGetBB already uses the batched C++ multiGet(), and all other benchmarks show consistent improvement after the changes: ## Before: ``` Benchmark (columnFamilyTestType) (keyCount) (keySize) (multiGetSize) (valueSize) Mode Cnt Score Error Units

Use do_validate flag to control timestamp based validation in WriteCommittedTxn::GetForUpdate (#12369)
Summary: When PR https://github.com/facebook/rocksdb/issues/9629 introduced user-defined timestamp support for `WriteCommittedTxn`, it adds this usage mandate for API `GetForUpdate` when UDT is enabled. The `do_validate` flag has to be true, and user should have already called `Transaction::SetReadTimestampForValidation` to set a read timestamp for validation. The rationale behind this mandate is this: 1) with do_vaildate = true, `GetForUpdate` could verify this relationships: let's denote the user-defined timestamp in db for the key as `Ts_db` and the read timestamp user set via `Transaction::SetReadTimestampForValidation` as `Ts_read`. UDT based validation will only pass if `Ts_db <= Ts_read`. |

Run internal cpp modernizer on RocksDB repo (#12398)
Summary: When internal cpp modernizer attempts to format rocksdb code, it will replace macro `ROCKSDB_NAMESPACE` with its default definition `rocksdb` when collapsing nested namespace. We filed a feedback for the tool T180254030 and the team filed a bug for this: https://github.com/llvm/llvm-project/issues/83452. At the same time, they suggested us to run the modernizer tool ourselves so future auto codemod attempts will be smaller.

Access DBImpl* and CFD* by CFHImpl* in Iterators (#12395)
Summary: In the current implementation of iterators, `DBImpl*` and `ColumnFamilyData*` are held in `DBIter` and `ArenaWrappedDBIter` for two purposes: tracing and Refresh() API. With the introduction of a new iterator called MultiCfIterator in PR https://github.com/facebook/rocksdb/issues/12153 , which is a cross-column-family iterator that maintains multiple DBIters as child iterators from a consistent database state, we need to make some changes to the existing implementation. The new iterator will still be exposed through the generic Iterator interface with an additional capability to return AttributeGroups (via `attribute_groups()`) which is a list of wide columns grouped by column family. For more information about AttributeGroup, please refer to previous PRs: https://github.com/facebook/rocksdb/issues/11925 #11943, and https://github.com/facebook/rocksdb/issues/11977. To be able to return AttributeGroup in the default single CF iterator created, access to `ColumnFamilyHandle*` within `DBIter` is necessary. However, this is not currently available in `DBIter`. Since `DBImpl*` and `ColumnFamilyData*` can be easily accessed via `ColumnFamilyHandleImpl*`, we have decided to replace the pointers to `ColumnFamilyData` and `DBImpl` in `DBIter` with a pointer to `ColumnFamilyHandleImpl`.

Deprecate some variants of Get and MultiGet (#12327)
Summary: A lot of variants of Get and MultiGet have been added to `include/rocksdb/db.h` over the years. Try to consolidate them by marking variants that don't return timestamps as deprecated. The underlying DB implementation will check and return Status::NotSupported() if it doesn't support returning timestamps and the caller asks for it.

Prefer static_cast in place of most reinterpret_cast (#12308)
Summary: The following are risks associated with pointer-to-pointer reinterpret_cast: * Can produce the "wrong result" (crash or memory corruption). IIRC, in theory this can happen for any up-cast or down-cast for a non-standard-layout type, though in practice would only happen for multiple inheritance cases (where the base class pointer might be "inside" the derived object). We don't use multiple inheritance a lot, but we do. * Can mask useful compiler errors upon code change, including converting between unrelated pointer types that you are expecting to be related, and converting between pointer and scalar types unintentionally. I can only think of some obscure cases where static_cast could be troublesome when it compiles as a replacement: * Going through `void*` could plausibly cause unnecessary or broken pointer arithmetic. Suppose we have `struct Derived: public Base1, public Base2`. If we have `Derived*` -> `void*` -> `Base2*` -> `Derived*` through reinterpret casts, this could plausibly work (though technical UB) assuming the `Base2*` is not dereferenced. Changing to static cast could introduce breaking pointer arithmetic. * Unnecessary (but safe) pointer arithmetic could arise in a case like `Derived*` -> `Base2*` -> `Derived*` where before the Base2 pointer might not have been dereferenced. This could potentially affect performance. With some light scripting, I tried replacing pointer-to-pointer reinterpret_casts with static_cast and kept the cases that still compile. Most occurrences of reinterpret_cast have successfully been changed (except for java/ and third-party/). 294 changed, 257 remain. A couple of related interventions included here: * Previously Cache::Handle was not actually derived from in the implementations and just used as a `void*` stand-in with reinterpret_cast. Now there is a relationship to allow static_cast. In theory, this could introduce pointer arithmetic (as described above) but is unlikely without multiple inheritance AND non-empty Cache::Handle. * Remove some unnecessary casts to void* as this is allowed to be implicit (for better or worse). Most of the remaining reinterpret_casts are for converting to/from raw bytes of objects. We could consider better idioms for these patterns in follow-up work. I wish there were a way to implement a template variant of static_cast that would only compile if no pointer arithmetic is generated, but best I can tell, this is not possible. AFAIK the best you could do is a dynamic check that the void* conversion after the static cast is unchanged.

Group SST write in flush, compaction and db open with new stats (#11910)
Summary: ## Context/Summary Similar to https://github.com/facebook/rocksdb/pull/11288, https://github.com/facebook/rocksdb/pull/11444, categorizing SST/blob file write according to different io activities allows more insight into the activity. For that, this PR does the following: - Tag different write IOs by passing down and converting WriteOptions to IOOptions - Add new SST_WRITE_MICROS histogram in WritableFileWriter::Append() and breakdown FILE_WRITE_{FLUSH|COMPACTION|DB_OPEN}_MICROS Some related code refactory to make implementation cleaner: - Blob stats - Replace high-level write measurement with low-level WritableFileWriter::Append() measurement for BLOB_DB_BLOB_FILE_WRITE_MICROS. This is to make FILE_WRITE_{FLUSH|COMPACTION|DB_OPEN}_MICROS include blob file. As a consequence, this introduces some behavioral changes on it, see HISTORY and db bench test plan below for more info. - Fix bugs where BLOB_DB_BLOB_FILE_SYNCED/BLOB_DB_BLOB_FILE_BYTES_WRITTEN include file failed to sync and bytes failed to write. - Refactor WriteOptions constructor for easier construction with io_activity and rate_limiter_priority - Refactor DBImpl::~DBImpl()/BlobDBImpl::Close() to bypass thread op verification - Build table - TableBuilderOptions now includes Read/WriteOpitons so BuildTable() do not need to take these two variables - Replace the io_priority passed into BuildTable() with TableBuilderOptions::WriteOpitons::rate_limiter_priority. Similar for BlobFileBuilder.

Add bounds checking to WBWIIteratorImpl and respect bounds of ReadOptions in Transaction (#11680)

In this way, the two sub itertors become more aligned from `BaseDeltaIterator`'s perspective. Like `DBIter`, the added bounds checking caps in either bound when seeking and disvalidates the `WBWIIteratorImpl` iterator when the lower bound is past or the upper bound is reached. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11680 Test Plan: - A simple test added to write_batch_with_index_test.cc to exercise the bounds checking in `WBWIIteratorImpl`. - A sophisticated test added to transaction_test.cc to assert that `Transaction` with different write policies honor bounds in `ReadOptions`.

Surface timestamp from db to the transaction iterator (#11847)
Summary: Provide an override implementation of `Iterator::timestamp` API for `BaseDeltaIterator` so that timestamp read from DB can be surfaced by an iterator created from inside of a transaction. The behavior of the API follows this rule: 1) If the entry is read from within the transaction, an empty `Slice` is returned as the timestamp, regardless of whether `Transaction::SetCommitTimestamp` is called. 2) If the entry is read from the DB, the corresponding `DBIter::timestamp()` API's result is returned.

Track full_history_ts_low per SuperVersion (#11784)
Summary: As discussed in https://github.com/facebook/rocksdb/issues/11730 , this PR tracks the effective `full_history_ts_low` per SuperVersion and update existing sanity checks for `ReadOptions.timestamp >= full_history_ts_low` to use this per SuperVersion `full_history_ts_low` instead. This also means the check is moved to happen after acquiring SuperVersion. There are two motivations for this: 1) Each time `full_history_ts_low` really come into effect to collapse history, a new SuperVersion is always installed, because it would involve either a Flush or Compaction, both of which change the LSM tree shape. We can take advantage of this to ensure that as long as this sanity check is passed, even if `full_history_ts_low` can be concurrently increased and collapse some history above the requested `ReadOptions.timestamp`, a read request won’t have visibility to that part of history through this SuperVersion that it already acquired. 2) the existing sanity check uses `ColumnFamilyData::GetFullHistoryTsLow` without locking the db mutex, which is the mutex all `IncreaseFullHistoryTsLow` operation is using when mutating this field. So there is a race condition. This also solve the race condition on the read path.

Group rocksdb.sst.read.micros stat by different user read IOActivity + misc (#11444)
Summary:
**Context/Summary:**
- Similar to https://github.com/facebook/rocksdb/pull/11288 but for user read such as `Get(), MultiGet(), DBIterator::XXX(), Verify(File)Checksum()`.
- For this, I refactored some user-facing `MultiGet` calls in `TransactionBase` and various types of `DB` so that it does not call a user-facing `Get()` but `GetImpl()` for passing the `ReadOptions::io_activity` check (see PR conversation)
- New user read stats breakdown are guarded by `kExceptDetailedTimers` since measurement shows they have 4-5% regression to the upstream/main.
- Misc
- More refactoring: with https://github.com/facebook/rocksdb/pull/11288, we complete passing `ReadOptions/IOOptions` to FS level. So we can now replace the previously [added](https://github.com/facebook/rocksdb/pull/9424) `rate_limiter_priority` parameter in `RandomAccessFileReader`'s `Read/MultiRead/Prefetch()` with `IOOptions::rate_limiter_priority`
- Also, `ReadAsync()` call time is measured in `SST_READ_MICRO` now

Use C++17 [[fallthrough]] in transaction_test.cc (#11663)
Summary: (Copied from https://www.internalfb.com/diff/D46606060) This diff makes its files safe for use with -Wimplicit-fallthrough. Now that we're using C+20 there's no reason not to use this C++17 feature to make our code safer. It's currently possible to write code like this: ``` switch(x){ case 1: foo1(); case 2: foo2(); break; case 3: foo3(); } ``` But that's scary because we don't know whether the fallthrough from case 1 was intentional or not. The -Wimplicit-fallthrough flag will make this an error. The solution is to either fix the bug by inserting break or indicating intention by using [[fallthrough]]; (from C++17). ``` switch(x){ case 1: foo1(); [[fallthrough]]; // Solution if we intended to fallthrough break; // Solution if we did not intend to fallthrough case 2: foo2(); break; case 3: foo3(); } ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/11663 Test Plan: Existing tests Reviewed By: jowlyzhang Differential Revision: D47961248 Pulled By: jaykorean fbshipit-source-id: 0d374c721bf1b328c14949dc5c17693da7311d03 |

Allow TryAgain in db_stress with optimistic txn, and refactoring (#11653)
Summary: In rare cases, optimistic transaction commit returns TryAgain. This change tolerates that intentional behavior in db_stress, up to a small limit in a row. This way, we don't miss a possible regression with excessive TryAgain, and trying again (rolling back the transaction) should have a well renewed chance of success as the writes will be associated with fresh sequence numbers. Also, some of the APIs were not clear about Transaction semantics, so I have clarified: * (Best I can tell....) Destroying a Transaction is safe without calling Rollback() (or at least should be). I don't know why it's a common pattern in our test code and examples to rollback before unconditional destruction. Stress test updated not to call Rollback unnecessarily (to test safe destruction). * Despite essentially doing what is asked, simply trying Commit() again when it returns TryAgain does not have a chance of success, because of the transaction being bound to the DB state at the time of operations before Commit. Similar logic applies to Busy AFAIK. Commit() API comments updated, and expanded unit test in optimistic_transaction_test. Also also, because I can't stop myself, I refactored a good portion of the transaction handling code in db_stress. * Avoid existing and new copy-paste for most transaction interactions with a new ExecuteTransaction (higher-order) function. * Use unique_ptr (nicely complements removing unnecessary Rollbacks) * Abstract out a pattern for safely calling std::terminate() and use it in more places. (The TryAgain errors we saw did not have stack traces because of "terminate called recursively".) Intended follow-up: resurrect use of `FLAGS_rollback_one_in` but also include non-trivial cases Pull Request resolved: https://github.com/facebook/rocksdb/pull/11653 Test Plan: this is the test :) Also, temporarily bypassed the new retry logic and boosted the chance of hitting TryAgain. Quickly reproduced the TryAgain error. Then re-enabled the new retry logic, and was not able to hit the error after running for tens of minutes, even with the boosted chances.

See https://app.circleci.com/pipelines/github/facebook/rocksdb/27912/workflows/4c63e5a8-597e-439d-8c7e-82308056af02/jobs/609648 and similar PR https://github.com/facebook/rocksdb/issues/11271 Had to fix the semantics of FaultInjectionTestFS Close() operations to allow a non-OK Close() to fulfill the obligation to close before destruction. To me, this is the obvious choice of Close contract, because what is the caller supposed to do if Close() fails and they still have an obligation to successfully close before object destruction? Call Close() in an infinite loop? Leak the object? I have added API comments to the Env and Filesystem Close() functions to clarify the contracts. Note that `DB::Close()` has one exception to this kind of Close contract, but it is clearly described in API comments and it is really only for catching programming mistakes, not for dealing with exogenous errors.

Add WaitForCompact with WaitForCompactOptions to public API (#11436)
Summary: Context: This is the first PR for WaitForCompact() Implementation with WaitForCompactOptions. In this PR, we are introducing `Status WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` in the public API. This currently utilizes the existing internal `WaitForCompact()` implementation (with default abort_on_pause = false). `abort_on_pause` has been moved to `WaitForCompactOptions&`. In the later PRs, we will introduce the following two options in `WaitForCompactOptions` 1. `bool flush = false` by default - If true, flush before waiting for compactions to finish. Must be set to true to ensure no immediate compactions (except perhaps periodic compactions) after closing and re-opening the DB. 2. `bool close_db = false` by default - If true, will also close the DB upon compactions finishing. 1. struct `WaitForCompactOptions` added to options.h and `abort_on_pause` in the internal API moved to the option struct. 2. `Status WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` introduced in `db.h` 3. Changed the internal WaitForCompact() to `WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` and checks for the `abort_on_pause` inside the option. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11436 Test Plan: Following tests added - `DBCompactionTest::WaitForCompactWaitsOnCompactionToFinish` - `DBCompactionTest::WaitForCompactAbortOnPauseAborted` - `DBCompactionTest::WaitForCompactContinueAfterPauseNotAborted` - `DBCompactionTest::WaitForCompactShutdownWhileWaiting` - `TransactionTest::WaitForCompactAbortOnPause` NOTE: `TransactionTest::WaitForCompactAbortOnPause` was added to use `StackableDB` to ensure the wrapper function is in place.

Improve memory efficiency of many OptimisticTransactionDBs (#11439)
Summary: Currently it's easy to use a ton of memory with many small OptimisticTransactionDB instances, because each one by default allocates a million mutexes (40 bytes each on my compiler) for validating transactions. It even puts a lot of pressure on the allocator by allocating each one individually! In this change: * Create a new object and option that enables sharing these buckets of mutexes between instances. This is generally good for load balancing potential contention as various DBs become hotter or colder with txn writes. About the only cases where this sharing wouldn't make sense (e.g. each DB usually written by one thread) are cases that would be better off with OccValidationPolicy::kValidateSerial which doesn't use the buckets anyway. * Allocate the mutexes in a contiguous array, for efficiency * Add an option to ensure the mutexes are cache-aligned. In several other places we use cache-aligned mutexes but OptimisticTransactionDB historically does not. It should be a space-time trade-off the user can choose. * Provide some visibility into the memory used by the mutex buckets with an ApproximateMemoryUsage() function (also used in unit testing) * Share code with other users of "striped" mutexes, appropriate refactoring for customization & efficiency (e.g. using FastRange instead of modulus) Pull Request resolved: https://github.com/facebook/rocksdb/pull/11439 Test Plan: unit tests added. Ran sized-up versions of stress test in unit test, including a before-and-after performance test showing no consistent difference. (NOTE: OptimisticTransactionDB not currently covered by db_stress!)

Remove wait_unscheduled from waitForCompact internal API (#11443)
Summary: Context: In pull request https://github.com/facebook/rocksdb/issues/11436, we are introducing a new public API `waitForCompact(const WaitForCompactOptions& wait_for_compact_options)`. This API invokes the internal implementation `waitForCompact(bool wait_unscheduled=false)`. The unscheduled parameter indicates the compactions that are not yet scheduled but are required to process items in the queue. In certain cases, we are unable to wait for compactions, such as during a shutdown or when background jobs are paused. It is important to return the appropriate status in these scenarios. For all other cases, we should wait for all compaction and flush jobs, including the unscheduled ones. The primary purpose of this new API is to wait until the system has resolved its compaction debt. Currently, the usage of `wait_unscheduled` is limited to test code. This pull request eliminates the usage of wait_unscheduled. The internal `waitForCompact()` API now waits for unscheduled compactions unless the db is undergoing a shutdown. In the event of a shutdown, the API returns `Status::ShutdownInProgress()`. Additionally, a new parameter, `abort_on_pause`, has been introduced with a default value of `false`. This parameter addresses the possibility of waiting indefinitely for unscheduled jobs if `PauseBackgroundWork()` was called before `waitForCompact()` is invoked. By setting `abort_on_pause` to `true`, the API will immediately return `Status::Aborted`. Furthermore, all tests that previously called `waitForCompact(true)` have been fixed.

Group rocksdb.sst.read.micros stat by IOActivity flush and compaction (#11288)
Summary: **Context:** The existing stat rocksdb.sst.read.micros does not reflect each of compaction and flush cases but aggregate them, which is not so helpful for us to understand IO read behavior of each of them. **Summary** - Update `StopWatch` and `RandomAccessFileReader` to record `rocksdb.sst.read.micros` and `rocksdb.file.{flush/compaction}.read.micros` - Fixed the default histogram in `RandomAccessFileReader` - New field `ReadOptions/IOOptions::io_activity`; Pass `ReadOptions` through paths under db open, flush and compaction to where we can prepare `IOOptions` and pass it to `RandomAccessFileReader` - Use `thread_status_util` for assertion in `DbStressFSWrapper` for continuous testing on we are passing correct `io_activity` under db open, flush and compaction Pull Request resolved: https://github.com/facebook/rocksdb/pull/11288 Test Plan: - **Stress test** - **Db bench 1: rocksdb.sst.read.micros COUNT ≈ sum of rocksdb.file.read.flush.micros's and rocksdb.file.read.compaction.micros's.** (without blob) - May not be exactly the same due to `HistogramStat::Add` only guarantees atomic not accuracy across threads. ``` ./db_bench -db=/dev/shm/testdb/ -statistics=true -benchmarks="fillseq" -key_size=32 -value_size=512 -num=50000 -write_buffer_size=655 -target_file_size_base=655 -disable_auto_compactions=false -compression_type=none -bloom_bits=3 (-use_plain_table=1 -prefix_size=10) ``` ``` // BlockBasedTable rocksdb.sst.read.micros P50 : 2.009374 P95 : 4.968548 P99 : 8.110362 P100 : 43.000000 COUNT : 40456 SUM : 114805 rocksdb.file.read.flush.micros P50 : 1.871841 P95 : 3.872407 P99 : 5.540541 P100 : 43.000000 COUNT : 2250 SUM : 6116 rocksdb.file.read.compaction.micros P50 : 2.023109 P95 : 5.029149 P99 : 8.196910 P100 : 26.000000 COUNT : 38206 SUM : 108689 // PlainTable Does not apply ``` - **Db bench 2: performance** **Read** SETUP: db with 900 files ``` ./db_bench -db=/dev/shm/testdb/ -benchmarks="fillseq" -key_size=32 -value_size=512 -num=50000 -write_buffer_size=655 -disable_auto_compactions=true -target_file_size_base=655 -compression_type=none ```run till convergence ``` ./db_bench -seed=1678564177044286 -use_existing_db=true -db=/dev/shm/testdb -benchmarks=readrandom[-X60] -statistics=true -num=1000000 -disable_auto_compactions=true -compression_type=none -bloom_bits=3 ``` Pre-change `readrandom [AVG 60 runs] : 21568 (± 248) ops/sec` Post-change (no regression, -0.3%) `readrandom [AVG 60 runs] : 21486 (± 236) ops/sec` **Compaction/Flush**run till convergence ``` ./db_bench -db=/dev/shm/testdb2/ -seed=1678564177044286 -benchmarks="fillseq[-X60]" -key_size=32 -value_size=512 -num=50000 -write_buffer_size=655 -disable_auto_compactions=false -target_file_size_base=655 -compression_type=none rocksdb.sst.read.micros COUNT : 33820 rocksdb.sst.read.flush.micros COUNT : 1800 rocksdb.sst.read.compaction.micros COUNT : 32020 ``` Pre-change `fillseq [AVG 46 runs] : 1391 (± 214) ops/sec; 0.7 (± 0.1) MB/sec` Post-change (no regression, ~-0.4%) `fillseq [AVG 46 runs] : 1385 (± 216) ops/sec; 0.7 (± 0.1) MB/sec` Reviewed By: ajkr Differential Revision: D44007011 Pulled By: hx235 fbshipit-source-id: a54c89e4846dfc9a135389edf3f3eedfea257132 |

Ensure LockWAL() stall cleared for UnlockWAL() return (#11172)
Summary: Fixes https://github.com/facebook/rocksdb/issues/11160 By counting the number of stalls placed on a write queue, we can check in UnlockWAL() whether the stall present at the start of UnlockWAL() has been cleared by the end, or wait until it's cleared. More details in code comments and new unit test. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11172 Test Plan: unit test added. Yes, it uses sleep to amplify failure on buggy behavior if present, but using a sync point to only allow new behavior would fail with the old code only because it doesn't contain the new sync point. Basically, using a sync point in UnlockWAL() could easily mask a regression by artificially limiting key behaviors. The test would only check that UnlockWAL() invokes code that *should* do the right thing, without checking that it *does* the right thing.
