(Apache-2.0 OR GPL-2.0-only) AND BSD-2-Clause
* Sat Nov 02 2024 Andreas Stieger <[email protected]>
- update to 9.7.4:
* Fix a leak of obsolete blob files left open until DB::Close().
This bug was introduced in version 9.4.0.
* Sun Oct 27 2024 Andrea Manzini <[email protected]>
- update to 9.7.3
* OPTIONS file to be loaded by remote worker is now preserved so that it does
not get purged by the primary host.
- update to 9.7.2
* Fixed a bug for surfacing write unix time:
Iterator::GetProperty("rocksdb.iterator.write-time") for non-L0 files.
- update to 9.7.1
* Fix for Several DB option settings could be lost through
GetOptionsFromString(), possibly elsewhere as well.
* Fix under counting of allocated memory in the compressed secondary cache
* Skip insertion of compressed blocks in the secondary cache if the
lowest_used_cache_tier DB option is kVolatileTier.
- update to 9.7.0
* New Features:
+ Make Cache a customizable class that can be instantiated by the object
registry.
+ Add new option prefix_seek_opt_in_only that makes iterators generally safer
+ Add a new table property "rocksdb.key.largest.seqno" which records the
largest sequence number of all keys in file.
* Behavior Changes
+ Changed the semantics of the BlobDB configuration option
blob_garbage_collection_force_threshold
+ Set write_dbid_to_manifest=true by default. This means DB ID will now be
preserved through backups, checkpoints, etc. by default. Also add
write_identity_file option
+ In FIFO compaction, compactions for changing file temperature (configured
by option file_temperature_age_thresholds) will compact one file at a time
+ Support ingesting db generated files using hard link
+ Add a new file ingestion option IngestExternalFileOptions::link_files
to hard link input files and preserve original files links after ingestion.
+ DB::Close now untracks files in SstFileManager, making avaialble any space
used by them
* Bug Fixes
+ Fix a bug in CompactRange() where result files may not be compacted in any
future compaction.
+ Fix handling of dynamic change of prefix_extractor with memtable prefix
filter.
+ Fix a bug with manual_wal_flush and auto error recovery from WAL failure
that may cause CFs to be inconsistent
* Thu Sep 12 2024 Andrea Manzini <[email protected]>
- update to 9.6.1:
* Fix correctness of MultiGet across column families with user timestamp.
- update to 9.6.0:
- New Features
* Best efforts recovery supports recovering to incomplete Version with a
clean seqno cut that presents a valid point in time view from the user's
perspective, if versioning history doesn't include atomic flush.
* New option BlockBasedTableOptions::decouple_partitioned_filters should
improve efficiency in serving read queries because filter and index
partitions can consistently target the configured metadata_block_size.
This option is currently opt-in.
* Introduce a new mutable CF option paranoid_memory_checks. It enables
additional validation on data integrity during reads/scanning. Currently,
skip list based memtable will validate key ordering during look up and scans.
- Public API Changes
* Add ticker stats to count file read retries due to checksum mismatch
* Adds optional installation callback function for remote compaction
- Behavior Changes
* There may be less intra-L0 compaction triggered by total L0 size being too
small. We now use compensated file size (tombstones are assigned some value
size) when calculating L0 size and reduce the threshold for L0 size limit.
This is to avoid accumulating too much data/tombstones in L0.
- Bug Fixes
* Make DestroyDB supports slow deletion when it's configured in SstFileManager.
The slow deletion is subject to the configured rate_bytes_per_sec, but not
subject to the max_trash_db_ratio.
* Fixed a bug where we set unprep_seqs_ even when WriteImpl() fails. This was
caught by stress test write fault injection in WriteImpl(). This may have
incorrectly caused iteration creation failure for unvalidated writes or
returned wrong result for WriteUnpreparedTxn::GetUnpreparedSequenceNumbers().
* Fixed a bug where successful write right after error recovery for last failed
write finishes causes duplicate WAL entries
* Fixed a data race involving the background error status in unordered_write
mode.
* Fix a bug where file snapshot functions like backup, checkpoint may attempt
to copy a non-existing manifest file. #12882
* Fix a bug where per kv checksum corruption may be ignored in MultiGet().
* Fix a race condition in pessimistic transactions that could allow multiple
transactions with the same name to be registered simultaneously, resulting
in a crash or other unpredictable behavior.
* Wed Aug 28 2024 Andrea Manzini <[email protected]>
- update to 9.5.2:
* Fix a race condition in pessimistic transactions that could allow
multiple transactions with the same name to be registered simultaneously,
resulting in a crash or other unpredictable behavior.
* Add ticker stats to count file read retries due to checksum mismatch
- update to 9.5.1:
* Make DestroyDB supports slow deletion when it's configured in
SstFileManager. The slow deletion is subject to the configured
rate_bytes_per_sec, but not subject to the max_trash_db_ratio.
- update to 9.5.0:
* Introduced new C API function rocksdb_writebatch_iterate_cf for column
family-aware iteration over the contents of a WriteBatch
* Add support to ingest SST files generated by a DB instead of SstFileWriter.
This can be enabled with experimental option
IngestExternalFileOptions::allow_db_generated_files.
* When calculating total log size for the log_size_for_flush argument
in CreateCheckpoint API, the size of the archived log will not be
included to avoid unnecessary flush
* Fix a major bug in which an iterator using prefix filtering and SeekForPrev
might miss data when the DB is using whole_key_filtering=false and
partition_filters=true.
* Fixed a bug where OnErrorRecoveryBegin() is not called before auto
recovery starts.
* Fixed a bug where event listener reads ErrorHandler's bg_error_ member
without holding db mutex(#12803).
* Fixed a bug in handling MANIFEST write error that caused the latest valid
MANIFEST file to get deleted, resulting in the DB being unopenable.
* Fixed a race between error recovery due to manifest sync or write failure
and external SST file ingestion. Both attempt to write a new manifest file,
which causes an assertion failure.
* Fix an issue where compactions were opening table files and reading table
properties while holding db mutex_.
* Reduce unnecessary filesystem queries and DB mutex acquires in creating
backups and checkpoints.
* Sat Jul 13 2024 Andreas Stieger <[email protected]>
- update to 9.4.0:
* Added a CompactForTieringCollectorFactory to auto trigger
compaction for tiering use case.
* Optimistic transactions and pessimistic transactions with the
WriteCommitted policy now support the GetEntityForUpdate API.
* Added a new "count" command to the ldb repl shell. By default,
it prints a count of keys in the database from start to end.
The options --from= and/or --to= can be specified to limit the
range.
* Deprecated names LogFile and VectorLogPtr in favor of new names
WalFile and VectorWalPtr.
* Introduce a new universal compaction option
CompactionOptionsUniversal::max_read_amp which allows user to
define the limit on the number of sorted runs separately from
the trigger for compaction (level0_file_num_compaction_trigger)
* Inactive WALs are immediately closed upon being fully sync-ed
rather than in a background thread.
* Bug Fixes
* Sat Jun 29 2024 Andreas Stieger <[email protected]>
- update to 9.3.1:
* Optimistic transactions and pessimistic transactions with the
WriteCommitted policy now support the GetEntity API.
* Added new Iterator property, "rocksdb.iterator.is-value-pinned",
for checking whether the Slice returned by Iterator::value()
can be used until the Iterator is destroyed.
* Optimistic transactions and WriteCommitted pessimistic
transactions now support the MultiGetEntity API.
* Optimistic transactions and pessimistic transactions with the
WriteCommitted policy now support the PutEntity API. Support
for read APIs and other write policies (WritePrepared,
WriteUnprepared) will be added later.
* Exposed block based metadata cache options via C API
* Exposed compaction pri via c api.
* Add a kAdmPolicyAllowAll option to TieredAdmissionPolicy that
admits all blocks evicted from the primary block cache into
the compressed secondary cache.
* CompactRange() with change_level=true on a CF with FIFO
compaction will return Status::NotSupported().
* External file ingestion with FIFO compaction will always ingest
to L0.
* bug fixes
* Thu May 23 2024 Andreas Stieger <[email protected]>
- update to 9.2.1:
* Added two options deadline and max_size_bytes for CacheDumper
to exit early
* API for wide-column point lookups with read-your-own-writes
consistency, and a batched versions of the same
* API to support programmatically read a SST file as a raw table
file
* API to wait for background purge to complete
* DeleteRange() will return NotSupported() if row_cache is
configured since they don't work together in some cases
* Deprecated CompactionOptions::compression
* Using OptionChangeMigration() to migrate from non-FIFO to FIFO
compaction with Options::compaction_options_fifo.
max_table_files_size > 0 can cause the whole DB to be dropped
right after migration if the migrated data is larger than
max_table_files_size
* Various behavior changes, and changes of defaults
* On distributed file systems that support file system level
checksum verification and reconstruction reads, RocksDB will
now retry a file read if the initial read fails RocksDB block
level or record level checksum verification. This applies to
MANIFEST file reads when the DB is opened, and to SST file
reads at all times.
* Bug fixes
* Mon Apr 22 2024 Andreas Stieger <[email protected]>
- update to 9.1.1:
* Adde an option GetMergeOperandsOptions::continue_cb to give
users the ability to end GetMergeOperands()'s lookup process
before all merge operands were found.
* Add sanity checks for ingesting external files that currently
checks if the user key comparator used to create the file is
compatible with the column family's user key comparator.
* Support ingesting external files for column family that has
user-defined timestamps in memtable only enabled
* On file systems that support storage level data checksum and
reconstruction, retry SST block reads for point lookups, scans,
and flush and compaction if there's a checksum mismatch on the
initial read.
* Some enhancements and fixes to experimental Temperature handling
features, including new default_write_temperature CF option and
opening an SstFileWriter with a temperature.
* WriteBatchWithIndex now supports wide-column point lookups via
the GetEntityFromBatch API.
* Implement experimental features:
API Iterator::GetProperty("rocksdb.iterator.write-time") to
allow users to get data's approximate write unix time and write
data with a specific write time via WriteBatch::TimedPut API.
- drop rocksdb-9.0.0-Fix-zstd-typo-in-cmake.patch, upstream
* Thu Apr 18 2024 Andreas Stieger <[email protected]>
- update to 9.0.1:
* Fix CMake Javadoc and source jar builds
* Fix Java SstFileMetaData to prevent throwing
java.lang.NoSuchMethodError
* Tue Mar 19 2024 Andreas Stieger <[email protected]>
- update to 9.0.0:
* Provide support for FSBuffer for point lookups. Also added
support for scans and compactions that don't go through prefetching.
* *Make SstFileWriter create SST files without persisting user
defined timestamps when the
Option.persist_user_defined_timestamps flag is set to false.
* Add support for user-defined timestamps in APIs
DeleteFilesInRanges and GetPropertiesOfTablesInRange.
* Mark wal_compression feature as production-ready. Currently
only compatible with ZSTD compression.
* Public API Changes, including incompatible changes
* format_version=6 is the new default setting in
BlockBasedTableOptions, for more robust data integrity
checking. DBs and SST files written with this setting cannot be
read by RocksDB versions before 8.6.0.
* Compactions can be scheduled in parallel in an additional
scenario: multiple files are marked for compaction within a
single column family
* For leveled compaction, RocksDB will try to do intra-L0
compaction if the total L0 size is small compared to Lbase.
* Users with atomic_flush=true are more likely to see the impact
of this change.
* Bug Fixes
- add rocksdb-9.0.0-Fix-zstd-typo-in-cmake.patch
* Wed Feb 28 2024 Andrea Manzini <[email protected]>
- update to 8.11.3:
* Bug Fixes
+ Fix a bug where older data of an ingested key can be returned for read when universal compaction is used
+ Apply appropriate rate limiting and priorities in more places.
- update to 8.11.0:
* New Features
+ Add new statistics: rocksdb.sst.write.micros measures time of each write to SST file
* Public API Changes
+ Added another enumerator kVerify to enum class FileOperationType in listener.h.
Update your switch statements as needed.
+ Add CompressionOptions to the CompressedSecondaryCacheOptions structure to allow users to specify
library specific options when creating the compressed secondary cache.
+ Deprecated several options: level_compaction_dynamic_file_size, ignore_max_compaction_bytes_for_input,
+ check_flush_compaction_key_order, flush_verify_memtable_count, compaction_verify_record_count,
fail_if_options_file_error, and enforce_single_del_contracts
+ Exposed options ttl via c api.
* Behavior Changes
+ rocksdb.blobdb.blob.file.write.micros expands to also measure time writing the header and footer.
Therefore the COUNT may be higher and values may be smaller than before. For stacked BlobDB,
it no longer measures the time of explictly flushing blob file.
+ Files will be compacted to the next level if the data age exceeds periodic_compaction_seconds
except for the last level.
+ Reduced the compaction debt ratio trigger for scheduling parallel compactions
+ For leveled compaction with default compaction pri (kMinOverlappingRatio),
files marked for compaction will be prioritized over files not marked when picking a file
from a level for compaction.
* Bug Fixes
+ Fix bug in auto_readahead_size that combined with IndexType::kBinarySearchWithFirstKey + fails
or iterator lands at a wrong key
+ Fixed some cases in which DB file corruption was detected but ignored on creating a backup with BackupEngine.
+ Fix bugs where rocksdb.blobdb.blob.file.synced includes blob files failed to get synced
and rocksdb.blobdb.blob.file.bytes.written includes blob bytes failed to get written.
+ Fixed a possible memory leak or crash on a failure (such as I/O error)
in automatic atomic flush of multiple column families.
+ Fixed some cases of in-memory data corruption using mmap reads with BackupEngine, sst_dump, or ldb.
+ Fixed issues with experimental preclude_last_level_data_seconds option that could interfere
with expected data tiering.
+ Fixed the handling of the edge case when all existing blob files become unreferenced.
Such files are now correctly deleted.
* Wed Feb 21 2024 Andreas Stieger <[email protected]>
- update to 8.10.2:
* Fix bug in auto_readahead_size that combined with
IndexType::kBinarySearchWithFirstKey + fails or iterator lands
at a wrong key
* Thu Jan 11 2024 Andreas Stieger <[email protected]>
- update to 8.10.0:
* Provide support for async_io to trim readahead_size by doing
block cache lookup
* Added initial wide-column support in WriteBatchWithIndex. This
includes the PutEntity API and support for wide columns in the
existing read APIs (GetFromBatch, GetFromBatchAndDB,
MultiGetFromBatchAndDB, and BaseDeltaIterator).
* Custom implementations of TablePropertiesCollectorFactory may
now return a nullptr collector to decline processing a file,
reducing callback overheads in such cases.
* Make ReadOptions.auto_readahead_size default true
* Bug fixes and performance improvements
* Tue Dec 12 2023 Andreas Stieger <[email protected]>
- update to 8.9.1:
* Add GetEntity() and PutEntity() API implementation for
Attribute Group support. Through the use of Column Families,
AttributeGroup enables users to logically group wide-column
entities.
* Make the EnableFileDeletion API not default to force enabling.
For users that rely on this default behavior and still want to
continue to use force enabling, they need to explicitly pass a
true to EnableFileDeletion.
* During off-peak hours defined by daily_offpeak_time_utc, the
compaction picker will select a larger number of files for
periodic compaction. This selection will include files that are
projected to expire by the next off-peak start time, ensuring
that these files are not chosen for periodic compaction outside
of off-peak hours.
* If an error occurs when writing to a trace file after
DB::StartTrace(), the subsequent trace writes are skipped to
avoid writing to a file that has previously seen error. In this
case, DB::EndTrace() will also return a non-ok status with info
about the error occured previously in its status message.
* Deleting stale files upon recovery are delegated to SstFileManger
if available so they can be rate limited.
* Make RocksDB only call TablePropertiesCollector::Finish() once.
* When WAL_ttl_seconds > 0, we now process archived WALs for
deletion at least every WAL_ttl_seconds / 2 seconds. Previously
it could be less frequent in case of small WAL_ttl_seconds values
when size-based expiration (WAL_size_limit_MB > 0 ) was
simultaneously enabled.
* Fix a crash or assertion failure bug in experimental new
HyperClockCache variant, especially when running with a
SecondaryCache.
* Fix a race between flush error recovery and db destruction that
can lead to db crashing.
* Fix some bugs in the index builder/reader path for user-
defined timestamps in Memtable only feature.
* Fri Nov 24 2023 Andrea Manzini <[email protected]>
- update to 8.8.1
* Bug fixes:
- Make the cache memory reservation accounting in Tiered cache
(primary and compressed secondary cache) more accurate to avoid over/under charging the secondary cache.
- Allow increasing the compressed_secondary_ratio in the Tiered cache after setting it to 0 to disable.
- update to 8.8.0
* New features:
- Introduce AttributeGroup by adding the first AttributeGroup support API, MultiGetEntity().
- Added new tickers rocksdb.fifo.{max.size|ttl}.compactions to count FIFO compactions
that drop files for different reasons
- Add an experimental offpeak duration awareness by setting DBOptions::daily_offpeak_time_utc in "HH:mm-HH:mm" format.
- Users can now change the max bytes granted in a single refill period (i.e, burst) during runtime
by SetSingleBurstBytes() for RocksDB rate limiter
* Public API Changes:
- The default value of DBOptions::fail_if_options_file_error changed from false to true.
- Add new Cache APIs GetSecondaryCacheCapacity() and GetSecondaryCachePinnedUsage()
to return the configured capacity, and cache reservation charged to the secondary cache.
* Behavior Changes:
- For non direct IO, eliminate the file system prefetching attempt for compaction read
when Options::compaction_readahead_size is 0
- During a write stop, writes now block on in-progress recovery attempts
- Deleting stale files upon recovery are delegated to SstFileManger if available so they can be rate limited.
* Bug Fixes
- Fix a bug in auto_readahead_size where first_internal_key of index blocks wasn't copied properly
resulting in corruption error when first_internal_key was used for comparison.
- Fixed a bug where compaction read under non direct IO still falls back to RocksDB internal prefetching
after file system's prefetching returns non-OK status other than Status::NotSupported()
- Add bounds check in WBWIIteratorImpl and make BaseDeltaIterator, WriteUnpreparedTxn and WritePreparedTxn
respect the upper bound and lower bound in ReadOption.
- Fixed the handling of wide-column base values in the max_successive_merges logic.
- Fixed a rare race bug involving a concurrent combination of Create/DropColumnFamily and/or Set(DB)Options
that could lead to inconsistency between (a) the DB's reported options state, (b) the DB options in effect,
and (c) the latest persisted OPTIONS file.
- Fixed a possible underflow when computing the compressed secondary cache share of memory reservations
while updating the compressed secondary to total block cache ratio.
* Performance Improvements
- Improved the I/O efficiency of DB::Open a new DB with create_missing_column_families=true and many column families.
- update to 8.7.3
* Behavior Changes:
- Deleting stale files upon recovery are delegated to SstFileManger if available so they can be rate limited.
* Public API Changes:
- Add new Cache APIs GetSecondaryCacheCapacity() and GetSecondaryCachePinnedUsage() to return
the configured capacity, and cache reservation charged to the secondary cache.
* Bug Fixes:
- Fixed a possible underflow when computing the compressed secondary cache share of memory reservations
while updating the compressed secondary to total block cache ratio.
- Fix an assertion failure when UpdeteTieredCache() is called in an idempotent manner.
* see more details at https://github.com/facebook/rocksdb/releases/tag/v8.7.3
* Sat Oct 28 2023 Andreas Stieger <[email protected]>
- update constraints for reliable building
* Mon Oct 09 2023 Andrea Manzini <[email protected]>
- update to 8.6.7
* Fixed a bug where compaction read under non direct IO still falls back to RocksDB internal prefetching after file system's prefetching returns non-OK status other than Status::NotSupported()
* For non direct IO, eliminate the file system prefetching attempt for compaction read when Options::compaction_readahead_size is 0
- update to 8.6.6
* Fix a bug with atomic_flush=true that can cause DB to stuck after a flush fails
* Fix a bug where RocksDB (with atomic_flush=false) can delete output SST files of pending flushes when a previous concurrent flush fails
* When the compressed secondary cache capacity is reduced to 0, it should be completely disabled. Before this fix, inserts and lookups would still go to the backing LRUCache
- update to 8.6.5
* Fixed a bug where rocksdb.file.read.verify.file.checksums.micros is not populated.
- update to 8.6.4
* Public API change: Add a column family option default_temperature that is used for file reading accounting purpose, such as io statistics, for files that don't have an explicitly set temperature.
- update to 8.6.3
* Fix a bug where if there is an error reading from offset 0 of a file from L1+ and that the file is not the first file in the sorted run, data can be lost in compaction and read/scan can return incorrect results.
* Fix a bug where iterator may return incorrect result for DeleteRange() users if there was an error reading from a file.
- update to 8.6.2
* Fix for async_io where during seek, when reading a block for seeking a target key in a file without any readahead, the iterator aligned the read on a page boundary and reading more than necessary. This increased the storage read bandwidth usage.
- update to 8.6.1
* Options::compaction_readahead_size 's default value is changed from 0 to 2MB.
* Compaction read performance will regress when Options::compaction_readahead_size is explicitly set to 0
- update to 8.6.0
* Added enhanced data integrity checking on SST files with new format_version=6.
* Add a new feature to trim readahead_size during scans upto upper_bound when iterate_upper_bound is specified.
* RocksDB will compare the number of input keys to the number of keys processed after each compaction.
* Add a CF option bottommost_file_compaction_delay to allow specifying the delay of bottommost level single-file compactions.
* Add support to allow enabling / disabling user-defined timestamps feature for an existing column family in combination with the in-Memtable only feature.
* Implement a new admission policy for the compressed secondary cache that admits blocks evicted from the primary cache with the hit bit set.
* Add a column family option memtable_max_range_deletions that limits the number of range deletions in a memtable.
* Add PutEntity API in sst_file_writer
* Add timeout in microsecond option to WaitForCompactOptions
* New statistics rocksdb.file.read.{get|multiget|db.iterator|verify.checksum|verify.file.checksums}.micros measure read time of block-based SST tables or blob files during db open, Get(), MultiGet(), using db iterator, VerifyFileChecksums() and VerifyChecksum(). They require stats level greater than StatsLevel::kExceptDetailedTimers.
* Add close_db option to WaitForCompactOptions to call Close() after waiting is done.
* Add a new compression option CompressionOptions::checksum for enabling ZSTD's checksum feature to detect corruption during decompression.
* Mark Options::access_hint_on_compaction_start related APIs as deprecated.
* Statistics rocksdb.sst.read.micros now includes time spent on multi read and async read into the file
* For Universal Compaction users, periodic compaction (option periodic_compaction_seconds) will be set to 30 days by default if block based table is used.
* Fix a bug in FileTTLBooster that can cause users with a large number of levels (more than 65) to see errors like "runtime error: shift exponent .. is too large.."
* Wed Sep 27 2023 Andreas Stieger <[email protected]>
- update to 8.5.4:
* Fix a bug where compaction read under non direct IO still falls
back to RocksDB internal prefetching after file system's
prefetching returns non-OK status other than
Status::NotSupported()
* For non direct IO, eliminate the file system prefetching
attempt for compaction read when
Options::compaction_readahead_size is 0
* Wed Sep 06 2023 Andrea Manzini <[email protected]>
- update to 8.5.3
* Fixed a race condition in GenericRateLimiter that could cause it to stop granting requests
- update to 8.5.2
* Fix a bug where iterator may return incorrect result for DeleteRange() users if there was an error reading from a file.
- update to 8.5.1
* Fix a bug where if there is an error reading from offset 0 of a file from L1+ and that the file is not the first file in the sorted run, data can be lost in compaction and read/scan can return incorrect results.
- update to 8.5.0
* Public API Changes:
Removed recently added APIs GeneralCache and MakeSharedGeneralCache() as our plan changed to stop exposing a general-purpose cache interface. The old forms of these APIs, Cache and NewLRUCache(), are still available, although general-purpose caching support will be dropped eventually.
* Behavior Changes
Option periodic_compaction_seconds no longer supports FIFO compaction: setting it has no effect on FIFO compactions. FIFO compaction users should only set option ttl instead.
Move prefetching responsibility to page cache for compaction read for non directIO use case
* Performance Improvements
In case of direct_io, if buffer passed by callee is already aligned, RandomAccessFileRead::Read will avoid realloacting a new buffer, reducing memcpy and use already passed aligned buffer.
Small efficiency improvement to HyperClockCache by reducing chance of compiler-generated heap allocations
* Bug Fixes
Fix use_after_free bug in async_io MultiReads when underlying FS enabled kFSBuffer. kFSBuffer is when underlying FS pass their own buffer instead of using RocksDB scratch in FSReadRequest. Right now it's an experimental feature.
Fix a bug in FileTTLBooster that can cause users with a large number of levels (more than 65) to see errors like "runtime error: shift exponent .. is too large.."
- see more on HISTORY.md (https://github.com/facebook/rocksdb/blob/main/HISTORY.md)
* Thu Jul 27 2023 Andrea Manzini <[email protected]>
- update to 8.3.2
* Bug Fixes:
Reduced cases of illegally using Env::Default() during static destruction by never destroying the internal PosixEnv itself
- update to 8.3.1
* Performance Improvements:
Fixed higher read QPS during DB::Open() reading files created prior to #11406,
- update to 8.3.0
* New Features:
Introduced a new option block_protection_bytes_per_key, which can be used to enable per key-value integrity protection for in-memory blocks in block cache
Improve the operational safety of publishing a DB or SST files to many hosts by using different block cache hash seeds on different hosts.
Introduced a new option CompactionOptionsFIFO::file_temperature_age_thresholds that allows FIFO compaction to compact files to different temperatures based on key age
Added a new ticker stat to count how many times RocksDB detected a corruption while verifying a block checksum: BLOCK_CHECKSUM_MISMATCH_COUNT.
New statistics rocksdb.file.read.db.open.micros that measures read time of block-based SST tables or blob files during db open.
New statistics tickers for various iterator seek behaviors and relevant filtering, as *_LEVEL_SEEK_*. (#11460)
* Public API Changes:
EXPERIMENTAL: Add new API DB::ClipColumnFamily to clip the key in CF to a certain range. It will physically deletes all keys outside the range including tombstones.
Add MakeSharedCache() construction functions to various cache Options objects, and deprecated the NewWhateverCache() functions with long parameter lists.
Changed the meaning of various Bloom filter stats (prefix vs. whole key), with iterator-related filtering only being tracked in the new *_LEVEL_SEEK_*. stats. (#11460)
* Behavior changes:
For x86, CPU features are no longer detected at runtime nor in build scripts, but in source code using common preprocessor defines.
This will likely unlock some small performance improvements on some newer hardware, but could hurt performance of the kCRC32c checksum,
which is no longer the default, on some "portable" builds. See PR #11419 for details.
* Bug Fixes:
Delete an empty WAL file on DB open if the log number is less than the min log number to keep
Delete temp OPTIONS file on DB open if there is a failure to write it out or rename it
* Performance Improvements:
Improved the I/O efficiency of prefetching SST metadata by recording more information in the DB manifest.
* Fri Apr 21 2023 Andreas Stieger <[email protected]>
- RocksDB 8.1.1
* Compaction output file cutting logic now considers range
tombstone start keys. For example, SST partitioner now may
receive ParitionRequest for range tombstone start keys.
* If the async_io ReadOption is specified for MultiGet or
NewIterator on a platform that doesn't support IO uring, the
option is ignored and synchronous IO is used.
* Add support for SecondaryCache with HyperClockCache
* New statistics and performance counters
* bug fixes
* API changes: Changed various functions and features in Cache
that are mostly relevant to custom implementations or wrappers
- build with shared gflags libs
* Sat Apr 15 2023 Andreas Stieger <[email protected]>
- add hardware constraints for reliable builds
