Vijay Nadimpalli	22028aa9ab	Compaction Reads should read no more than compaction_readahead_size bytes, when set! (#5498 ) Summary: As a result of https://github.com/facebook/rocksdb/issues/5431 the compaction_readahead_size given by a user was not used exactly, the reason being the code behind readahead for user-read and compaction-read was unified in the above PR and the behavior for user-read is to read readahead_size+n bytes (see FilePrefetchBuffer::TryReadFromCache method). Before the unification the ReadaheadRandomAccessFileReader used compaction_readahead_size as it is. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5498 Test Plan: Ran strace command : strace -e pread64 -f -T -t ./db_compaction_test --gtest_filter=DBCompactionTest.PartialManualCompaction In the test the compaction_readahead_size was configured to 2MB and verified the pread syscall did indeed request 2MB. Before the change it was requesting more than 2MB.

Yi Wu	2730fe693e	Fix ingested file and direcotry not being sync (#5435 ) Summary: It it not safe to assume application had sync the SST file before ingest it into DB. Also the directory to put the ingested file needs to be fsync, otherwise the file can be lost. For integrity of RocksDB we need to sync the ingested file and directory before apply the change to manifest. Also syncing after writing global sequence when write_global_seqno=true was removed in https://github.com/facebook/rocksdb/issues/4172. Adding it back. Fixes https://github.com/facebook/rocksdb/issues/5287. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5435 Test Plan: Test ingest file with ldb command and observe fsync/fdatasync in strace output. Tried both move_files=true and move_files=false. https://gist.github.com/yiwu-arbug/650a4023f57979056d83485fa863bef9 More test suggestions are welcome.

haoyuhuang	705b8eecb4	Add more callers for table reader. (#5454 ) Summary: This PR adds more callers for table readers. These information are only used for block cache analysis so that we can know which caller accesses a block. 1. It renames the BlockCacheLookupCaller to TableReaderCaller as passing the caller from upstream requires changes to table_reader.h and TableReaderCaller is a more appropriate name. 2. It adds more table reader callers in table/table_reader_caller.h, e.g., kCompactionRefill, kExternalSSTIngestion, and kBuildTable. This PR is long as it requires modification of interfaces in table_reader.h, e.g., NewIterator.

feilongliu	0b0cb6f1a2	Fix segfalut in ~DBWithTTLImpl() when called after Close() (#5485 ) Summary: ~DBWithTTLImpl() fails after calling Close() function (will invoke the Close() function of DBImpl), because the Close() function deletes default_cf_handle_ which is used in the GetOptions() function called in ~DBWithTTLImpl(), hence lead to segfault. Fix by creating a Close() function for the DBWithTTLImpl class and do the close and the work originally in ~DBWithTTLImpl(). If the Close() function is not called, it will be called in the ~DBWithTTLImpl() function.

Sagar Vemuri	68614a9608	Fix AlignedBuffer's usage in Encryption Env (#5396 ) Summary: The usage of `AlignedBuffer` in env_encryption.cc writes and reads to/from the AlignedBuffer's internal buffer directly without going through AlignedBuffer's APIs (like `Append` and `Read`), causing encapsulation to break in some cases. The writes are especially problematic as after the data is written to the buffer (directly using either memmove or memcpy), the size of the buffer is not updated ... causing the AlignedBuffer to lose track of the encapsulated buffer's current size. Fixed this by updating the buffer size after every write. Todo for later: Add an overloaded method to AlignedBuffer to support a memmove in addition to a memcopy. Encryption env does a memmove, and hence I couldn't switch to using `AlignedBuffer.Append()`.

Yanqin Jin	f287f8dc93	Fix a bug caused by secondary not skipping the beginning of new MANIFEST (#5472 ) Summary: While the secondary is replaying after the primary, the primary may switch to a new MANIFEST. The secondary is already able to detect and follow the primary to the new MANIFEST. However, the current implementation has a bug, described as follows. The new MANIFEST's first records have been generated by VersionSet::WriteSnapshot to describe the current state of the column families and the db as of the MANIFEST creation. Since the secondary instance has already finished recovering upon start, there is no need for the secondary to process these records. Actually, if the secondary were to replay these records, the secondary may end up adding the same SST files again to each column family, causing consistency checks done by VersionBuilder to fail. Therefore, we record the number of records to skip at the beginning of the new MANIFEST and ignore them.

haoyuhuang	bcfc53b436	Block cache tracing: Fix minor bugs with downsampling and some benchmark results. (#5473 ) Summary: As the code changes for block cache tracing are almost complete, I did a benchmark to compare the performance when block cache tracing is enabled/disabled. With 1% downsampling ratio, the performance overhead of block cache tracing is negligible. When we trace all block accesses, the throughput drops by 6 folds with 16 threads issuing random reads and all reads are served in block cache.

Yanqin Jin	7d8d56413d	Override check consistency for DBImplSecondary (#5469 ) Summary: `DBImplSecondary` calls `CheckConsistency()` during open. In the past, `DBImplSecondary` did not override this function thus `DBImpl::CheckConsistency()` is called. The following can happen. The secondary instance is performing consistency check which calls `GetFileSize(file_path)` but the file at `file_path` is deleted by the primary instance. `DBImpl::CheckConsistency` does not account for this and fails the consistency check. This is undesirable. The solution is that, we call `DBImpl::CheckConsistency()` first. If it passes, then we are good. If not, we give it a second chance and handles the case of file(s) being deleted.

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.

Levi Tamasi	ba64a4cf52	Revert "Reduce iterator key comparison for upper/lower bound check (#5111 )" (#5440 ) Summary: This reverts commit `f3a7847598`.

Yanqin Jin	7177dc46a1	Handle missing WAL in secondary mode (#5323 ) Summary: In secondary mode, it is possible that the secondary lists the primary's WAL directory, finds a WAL and tries to open it. It is possible that the primary deletes the WAL after secondary listing dir but before the secondary opening it. Then the secondary will fail to open the WAL file with a PathNotFound status. In this case, we can return OK without replaying WAL and optionally replay more MANIFEST. Test Plan (on my dev machine): Without this PR, the following will fail several times out of 100 runs. ``` ~/gtest-parallel/gtest-parallel -r 100 -w 16 ./db_secondary_test --gtest_filter=DBSecondaryTest.SwitchToNewManifestDuringOpen ``` With this PR, the above should always succeed.

sdong	58c4aee42e	TransactionUtil::CheckKey() to skip unnecessary history (#4941 ) Summary: If a memtable definitely covers a key, there isn't a need to check older memtables. We can skip them by checking the earliest sequence number.

Maysam Yabandeh	c8c1a549f0	Avoid deadlock between mutex_ and log_write_mutex_ (#5437 ) Summary: To avoid deadlock mutex_ should never be acquired before log_write_mutex_. The patch documents that and also fixes one case in ::FlushWAL that acquires mutex_ through ::WriteStatusCheck when it already holds lock on log_write_mutex_.

Maysam Yabandeh	b2584577fa	Remove global locks from FlushScheduler (#5372 ) Summary: FlushScheduler's methods are instrumented with debug-time locks to check the scheduler state against a simple container definition. Since https://github.com/facebook/rocksdb/pull/2286 the scope of such locks are widened to the entire methods' body. The result is that the concurrency tested during testing (in debug mode) is stricter than the concurrency level manifested at runtime (in release mode). The patch reverts this change to reduce the scope of such locks.
