Introduce a dedicated class to represent blob values (#10571)
Summary: The patch introduces a new class called `BlobContents`, which represents a single uncompressed blob value. We currently use `std::string` for this purpose; `BlobContents` is somewhat smaller but the primary reason for a dedicated class is that it enables certain improvements and optimizations like eliding a copy when inserting a blob into the cache, using custom allocators, or more control over and better accounting of the memory usage of cached blobs (see https://github.com/facebook/rocksdb/issues/10484). (We plan to implement these in subsequent PRs.)

Ensure writes to WAL tail during `FlushWAL(true /* sync */)` will be synced (#10560)
Summary: WAL append and switch can both happen between `FlushWAL(true /* sync */)`'s sync operations and its call to `MarkLogsSynced()`. We permit this since locks need to be released for the sync operations. Such an appended/switched WAL is both inactive and incompletely synced at the time `MarkLogsSynced()` processes it. Prior to this PR, `MarkLogsSynced()` assumed all inactive WALs were fully synced and removed them from consideration for future syncs. That was wrong in the scenario described above and led to the latest append(s) never being synced. This PR changes `MarkLogsSynced()` to only remove inactive WALs from consideration for which all flushed data has been synced. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10560 Test Plan: repro unit test for the scenario described above.

CI benchmarks refine configuration (#10514)
Summary: CI benchmarks refine configuration Run only “essential” benchmarks, but for longer Fix (reduce) the NUM_KEYS to ensure cached behaviour Reduce level size to try to ensure more levels Refine test durations again, more time per test, but fewer tests. In CI benchmark mode, the only read test is readrandom. There are still 3 mostly-read tests. Goal is to squeeze complete run a little bit inside 1 hour so it doesn’t clash with the next run (cron scheduled for main branch), but it gets to run as long as possible, so that results are as credible as possible. Reduce thread count to physical capacity, in an attempt to reduce throughput variance for write heavy tests. See Mark Callaghan’s comments in related documentation..

Disable db_stress features incompatible with unsynced data dropping when sync_fault_injection=1 (#10559)

Add Iterator test against expected state to stress test (#10538)
Summary: As mentioned in https://github.com/facebook/rocksdb/pull/5506#issuecomment-506021913, `db_stress` does not have much verification for iterator correctness. It has a `TestIterate()` function, but that is mainly for comparing results between two iterators, one with `total_order_seek` and the other optionally sets auto_prefix, upper/lower bounds. Commit 49a0581ad2462e31aa3f768afa769e0d33390f33 added a new `TestIterateAgainstExpected()` function that compares iterator against expected state. It locks a range of keys, creates an iterator, does a random sequence of `Next/Prev` and compares against expected state. This PR is based on that commit, the main changes include some logs (for easier debugging if a test fails), a forward and backward scan to cover the entire locked key range, and a flag for optionally turning on this version of Iterator testing. Added constraint that the checks against expected state in `TestIterateAgainstExpected()` and in `TestGet()` are only turned on when `--skip_verifydb` flag is not set. Remove the change log introduced in https://github.com/facebook/rocksdb/issues/10553. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10538 Test Plan: Run `db_stress` with `--verify_iterator_with_expected_state_one_in=1`, and a large `--iterpercent` and `--num_iterations`. Checked `op_logs` manually to ensure expected coverage. Tweaked part of the code in https://github.com/facebook/rocksdb/issues/10449 and stress test was able to catch it. - internally run various flavor of crash test Reviewed By: ajkr Differential Revision: D38847269 Pulled By: cbi42 fbshipit-source-id: 8b4402a9bba9f6cfa08051943cd672579d489599 |

WritableFileWriter to allow operation after failure when SyncWithoutFlush() is involved (#10555)
Summary: https://github.com/facebook/rocksdb/pull/10489 adds an assertion in most functions in WritableFileWriter to check no previous error. However, it only works without calling SyncWithoutFlush(). The nature of SyncWithoutFlush() makes two concurrent call fails to check status code of each other and causing assertion failure. Fix the problem by skipping the check after SyncWithoutFlush() is called and not check status code in SyncWithoutFlush(). Since the original change was not officially released yet, the fix isn't added to HISTORY.md.

Update `TestGet()` to verify against expected state (#10553)
Summary: updated `TestGet()` in `no_batched_op_stress` to check the result of `Get()` operations against expected state (`expected_state_manager_`). More specifically, if `Get()` finds a key, expected state should not have `DELETION_SENTINEL` for the same key, and if `Get()` returns NotFound for a key, expected state should not have the key. One intention for this change it to verify correctness of code path change regarding range tombstones. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10553 Test Plan: run db_stress with nonzero readpercent: `./db_stress_branch --readpercent=57 --prefixpercent=4 --writepercent=25 -delpercent=5 --iterpercent=5 --delrangepercent=4`.

Add missing synchronization in TestFSWritableFile (#10544)

--checkpoint_one_in=1000 ``` The race is due to concurrent access from [checkpoint's WAL sync](https://github.com/facebook/rocksdb/blob/7.4.fb/utilities/fault_injection_fs.cc#L324) and [db put's WAL write when ‘sync_fault_injection=1 ‘](https://github.com/facebook/rocksdb/blob/7.4.fb/utilities/fault_injection_fs.cc#L208) to the `state_` on the same WAL `TestFSWritableFile` under the missing

MultiGet async IO across multiple levels (#10535)
Summary: This PR exploits parallelism in MultiGet across levels. It applies only to the coroutine version of MultiGet. Previously, MultiGet file reads from SST files in the same level were parallelized. With this PR, MultiGet batches with keys distributed across multiple levels are read in parallel. This is accomplished by splitting the keys not present in a level (determined by bloom filtering) into a separate batch, and processing the new batch in parallel with the original batch. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10535 Test Plan: 1. Ensure existing MultiGet unit tests pass, updating them as necessary 2. New unit tests - TODO 3.

Add support for wide-column point lookups (#10540)
Summary: The patch adds a new API `GetEntity` that can be used to perform wide-column point lookups. It also extends the `Get` code path and the `MemTable` / `MemTableList` and `Version` / `GetContext` logic accordingly so that wide-column entities can be served from both memtables and SSTs. If the result of a lookup is a wide-column entity (`kTypeWideColumnEntity`), it is passed to the application in deserialized form; if it is a plain old key-value (`kTypeValue`), it is presented as a wide-column entity with a single default (anonymous) column. (In contrast, regular `Get` returns plain old key-values as-is, and returns the value of the default column for wide-column entities, see https://github.com/facebook/rocksdb/issues/10483 .) The result of `GetEntity` is a self-contained `PinnableWideColumns` object. `PinnableWideColumns` contains a `PinnableSlice`, which either stores the underlying data in its own buffer or holds on to a cache handle. It also contains a `WideColumns` instance, which indexes the contents of the `PinnableSlice`, so applications can access the values of columns efficiently. There are several pieces of functionality which are currently not supported for wide-column entities: there is currently no `MultiGetEntity` or wide-column iterator; also, `Merge` and `GetMergeOperands` are not supported, and there is no `GetEntity` implementation for read-only and secondary instances. We plan to implement these in future PRs.

Fix the memory leak in db_stress tests that are caused by `FaultInjectionSecondaryCache` and add `CompressedSecondaryCache` into stress tests. (#10523)
Summary:
1. Fix the memory leak in db_stress tests that are caused by `FaultInjectionSecondaryCache`. To address the test requirements for both CompressedSecondaryCache and CachlibWrapper, a new class variable `base_is_compressed_sec_cache_` is added to determine the different behaviors in `Lookup()` and `WaitAll()`.
2. Add `CompressedSecondaryCache` into stress tests.
Before this PR, memory leak is reported during crash tests if `CompressedSecondaryCache` is in stress tests. One example is shown as follows:
```
==70722==ERROR: LeakSanitizer: detected memory leaks

Prevent a case of WriteBufferManager flush thrashing (#6364)
Summary: Previously, the flushes triggered by `WriteBufferManager` could affect the same CF repeatedly if it happens to get consecutive writes. Such flushes are not particularly useful for reducing memory usage since they switch nearly-empty memtables to immutable while they've just begun filling their first arena block. In fact they may not even reduce the mutable memory count if they involve replacing one mutable memtable containing one arena block with a new mutable memtable containing one arena block. Further, if such switches happen even a few times before a flush finishes, the immutable memtable limit will be reached and writes will stall. This PR adds a heuristic to not switch memtables to immutable for CFs that already have one or more immutable memtables awaiting flush. There is a memory usage regression if the user continues writing to the same CF, that DB does not have any CFs eligible for switching, flushes are not finishing, and the `WriteBufferManager` was constructed with `allow_stall=false`. Before, it would grow by switching nearly empty memtables until writes stall. Now, it would grow by filling memtables until writes stall. This feels like an acceptable behavior change because users who prefer to stall over violate the memory limit should be using `allow_stall=true`, which is unaffected by this PR.

Fix range deletion handling in async MultiGet (#10534)
Summary: The fix in https://github.com/facebook/rocksdb/issues/10513 was not complete w.r.t range deletion handling. It didn't handle the case where a file with a range tombstone covering a key also overlapped another key in the batch. In that case, ```mget_range``` would be non-empty. However, ```mget_range``` would only have the second key and, therefore, the first key would be skipped when iterating through the range tombstones in ```TableCache::MultiGet```. Test plan - 1.

Add a blob-specific cache priority (#10461)
Summary: RocksDB's `Cache` abstraction currently supports two priority levels for items: high (used for frequently accessed/highly valuable SST metablocks like index/filter blocks) and low (used for SST data blocks). Blobs are typically lower-value targets for caching than data blocks, since 1) with BlobDB, data blocks containing blob references conceptually form an index structure which has to be consulted before we can read the blob value, and 2) cached blobs represent only a single key-value, while cached data blocks generally contain multiple KVs. Since we would like to make it possible to use the same backing cache for the block cache and the blob cache, it would make sense to add a new, lower-than-low cache priority level (bottom level) for blobs so data blocks are prioritized over them.

Derive cache keys from SST unique IDs (#10394)
Summary: ... so that cache keys can be derived from DB manifest data before reading the file from storage--so that every part of the file can potentially go in a persistent cache. See updated comments in cache_key.cc for technical details. Importantly, the new cache key encoding uses some fancy but efficient math to pack data into the cache key without depending on the sizes of the various pieces. This simplifies some existing code creating cache keys, like cache warming before the file size is known. This should provide us an essentially permanent mapping between SST unique IDs and base cache keys, with the ability to "upgrade" SST unique IDs (and thus cache keys) with new SST format_versions. These cache keys are of similar, perhaps indistinguishable quality to the previous generation. Before this change (see "corrected" days between collision): ``` ./cache_bench -stress_cache_key -sck_keep_bits=43 18 collisions after 2 x 90 days, est 10 days between (1.15292e+19 corrected) ``` After this change (keep 43 bits, up through 50, to validate "trajectory" is ok on "corrected" days between collision): ``` 19 collisions after 3 x 90 days, est 14.2105 days between (1.63836e+19 corrected) 16 collisions after 5 x 90 days, est 28.125 days between (1.6213e+19 corrected) 15 collisions after 7 x 90 days, est 42 days between (1.21057e+19 corrected) 15 collisions after 17 x 90 days, est 102 days between (1.46997e+19 corrected) 15 collisions after 49 x 90 days, est 294 days between (2.11849e+19 corrected) 15 collisions after 62 x 90 days, est 372 days between (1.34027e+19 corrected) 15 collisions after 53 x 90 days, est 318 days between (5.72858e+18 corrected) 15 collisions after 309 x 90 days, est 1854 days between (1.66994e+19 corrected) ``` However, the change does modify (probably weaken) the "guaranteed unique" promise from this > SST files generated in a single process are guaranteed to have unique cache keys, unless/until number session ids * max file number = 2**86 to this (see https://github.com/facebook/rocksdb/issues/10388) > With the DB id limitation, we only have nice guaranteed unique cache keys for files generated in a single process until biggest session_id_counter and offset_in_file reach combined 64 bits I don't think this is a practical concern, though.

LOG more info on oldest snapshot and sequence numbers (#10454)
Summary: The info LOG file does not currently give any direct information about the existence of old, live snapshots, nor how to estimate wall time from a sequence number within the scope of LOG history. This change addresses both with: * Logging smallest and largest seqnos for generated SST files, which can help associate sequence numbers with write time (based on flushes). * Logging oldest_snapshot_seqno for each compaction, which (along with that seqno info) helps us to determine how much old data might be kept around for old (leaked?) snapshots. Including the date here I thought might be excessive. I wanted to log the date and seqno of the oldest snapshot with periodic stats, but the current structure of the code doesn't really support that because `DumpDBStats` doesn't have access to the DB object.

Fix regression issue of too large score (#10518)
Summary: https://github.com/facebook/rocksdb/pull/10057 caused a regression bug: since the base level size is not adjusted based on L0 size anymore, L0 score might become very large. This makes compaction heavily favor L0->L1 compaction against L1->L2 compaction, and cause in some cases, data stuck in L1 without being moved down. We fix calculating a score of L0 by size(L0)/size(L1) in the case where L0 is large.. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10518 Test Plan: run db_bench against data on tmpfs and watch the behavior of data stuck in L1 goes away.

Fix wrong value passed in compaction filter in BlobDB (#10391)
Summary: New blobdb has a bug in compaction filter, where `blob_value_` is not reset for next iterated key. This will cause blob_value_ not empty and previous value read from blob is passed into the filter function for next key, even if its value is not in blob. Fixed by reseting regardless of key type.

Enable ClockCache in DB block cache test (#10482)
Summary: A test in db_block_cache_test.cc was skipping ClockCache due to the 16-byte key length requirement. We fixed this. Along the way, we fixed a bug in ApplyToSomeEntries, which assumed the function being applied could modify handle metadata, and thus took an exclusive reference. This is incompatible with calls that need to inspect every element (including externally referenced ones) to gather stats.

Include minimal contextual information in `CompactionIterator` (#10505)
Summary: The main purpose is to make debugging easier without sacrificing performance. Instead of using a boolean variable for `CompactionIterator::valid_`, we can extend it to an `uint8_t`, using the LSB to denote if the compaction iterator is valid and 4 additional bits to denote where the iterator is set valid inside `NextFromInput()`. Therefore, when the control flow reaches `PrepareOutput()` and hits assertion there, we can have a better idea of what has gone wrong. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10505 Test Plan: make check ``` TEST_TMPDIR=/dev/shm/rocksdb time ./db_bench -compression_type=none -write_buffer_size=1073741824 -benchmarks=fillseq,flush ``` The above command has a 'flush' benchmark which uses `CompactionIterator`.

Fix MultiGet range deletion handling and a memory leak (#10513)
Summary: This PR fixes 2 bugs introduced in https://github.com/facebook/rocksdb/issues/10432 - 1. If the bloom filter returned a negative result for all MultiGet keys in a file, the range tombstones in that file were being ignored, resulting in incorrect results if those tombstones covered a key in a higher level. 2. If all the keys in a file were filtered out in `TableCache::MultiGetFilter`, the table cache handle was not being released. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10513 Test Plan: Add a new unit test that fails without this fix Reviewed By: akankshamahajan15 Differential Revision: D38548739 Pulled By: anand1976 fbshipit-source-id: a741a1e25d2e991d63f038100f126c2dc404a87c |

Reset blob value as soon as it's not needed in DBIter (#10490)
Summary: We have recently added caching support to BlobDB, and separately, implemented an optimization where reading blobs from the cache results in the cache handle being transferred to the target `PinnableSlice` (as opposed to the contents getting copied). With these changes, it makes sense to reset the `PinnableSlice` storing the blob value in `DBIter` as soon as we move to a different iterator position to prevent us from holding on to the cache handle any longer than necessary.

Make queries return the value of the default column for wide-column entities (#10483)
Summary: The patch adds support for wide-column entities to the existing query APIs (`Get`, `MultiGet`, and iterator). Namely, when during a query a wide-column entity is encountered, we will return the value of the default (anonymous) column as the result. Later, we plan to add wide-column specific query APIs which will enable retrieving entire wide-column entities or a subset of their columns.

Change `bottommost_temperture` to `last_level_temperture` (#10471)
Summary: Change tiered compaction feature from `bottommost_temperture` to `last_level_temperture`. The old option is kept for migration purpose only, which is behaving the same as `last_level_temperture` and it will be removed in the next release.
