Full Changelog: speedb/v2.5.0...speedb/v2.6.0
v2.5.0
Release date: 14-June-2023 | Based on RocksDB 8.1.1
New Features
Dirty memory: connect wbm to global delay : Delay writes gradually based on memory usage of the WriteBufferManager (WBM) in order to gain stability. To use this feature, pass allow_stall = true to the ctor of WBM and the db needs to be opened with options.use_dynamic_delay = true. by @Yuval-Ariel in #423
Prevent flush entry followed delete operations currently during memtable flush , if the key has a match key in the delete range table and this record has no snapshot related to it, we still write it with its value to the SST file. This feature keeps only the delete record and reduces SST size for later compaction. by @ayulas in #418 (#411)
Enhancements
Log: Add the CF name and job ID to all compaction job traces by @udi-speedb in #511
Log: Display cf names in rolled logs with their options by @udi-speedb in #518
Log: Report the name of cf-s whose options are skipped in the log by @udi-speedb in #520
db_stress: Add cost_write_buffer_to_cache flag by @udi-speedb in #513
Bug Fixes
Sanitize max_num_parallel_flushes in WBM if 0 by @udi-speedb in #515
WriteController: fix for stop while shutting down. Also switch to waiting a sec on the CV each time. This is required since a bg error * doesn't signal the CV in the WriteController. by @Yuval-Ariel in #499
Fixed UnlockWALStallCleared test in utilities/transactions/transaction_test.cc by @Yuval-Ariel in #514
Always assume optimize_filters_for_memory=false when creating a paired bloom filter by @udi-speedb in #528
db_bench and stress: fixed WBM initiation by @udi-speedb in #510
db_bench: Create a WBM once for all db-s regardless of their use in different groups by @udi-speedb in #551
Makefile: Remove pycache artifacts after running gtest-parallel #495
AVX512: fix disabling other optimizations by @Yuval-Ariel in #489 #489
Miscellaneous
Print optimize_filters_for_memory option to the log by @udi-speedb in #537

v2.0.0
Release date: 04-August-2022 | Based on RocksDB 7.2.2
New Features
Added a new hash based memtable that supports concurrent reads and writes
Added ability to create MemTableFactory from URI/string to tools
Bug Fixes
Avoid comparing Status using == as it compares only status codes. The comparison breaks when comparing against status::NoSpace() since it has a status code of
Code::kIOErrorand only a subcode ofSubCode::kNoSpaceFixed snapshots leak in optimistic_transaction_example: whenever the example is run under ASan, snapshots are acquired but not released, resulting in a memory leak error.
ldb: fix get to print the entire value
db_bench: fix Rocksdb bug of last_ref assertion. Test fails to delete multi-dbs correctly.
db_bench: fix SeekRandom and ReadRandomWriteRandom to work on all CFs instead of the default
db_bench to report accurate response time when using rate limit
db_test: add test for - forward the incomplete status on no_io (facebook/rocksdb#8485)
CMake: use the old plugin infra and add support for *_FUNC registration
Miscellaneous
LOG: Print write_buffer_manager size to LOG
LOG: change log header to SpeeDB
LOG & db_bench: metadata_cache_options - print to LOG and support its configuration in db_bench
db_impl: use unique_ptr in DBImpl::Open for nicer memory management
Explicitly compare the SuperVersion pointer in column_family
Rename rocksdb threads to speedb
Add a version number to Speedb builds
Clang-Format: Do not include third-party code as any changes are either version updates or fixes.
