- Added support for Slovak, which is now auto-detected from terms [@valeriansaliou, 19412ce].
- Added Slovak stopwords [@valeriansaliou, 19412ce].
- Dependencies have been bumped to latest versions (namely:
whatlang) [@valeriansaliou, 19412ce].
- Fixed multiple deadlocks, which where not noticed in practice by running Sonic at scale, but that are still theoretically possible [@BurtonQin, #213, #211].
- Added support for Latin, which is now auto-detected from terms [@valeriansaliou, e6c5621].
- Added Latin stopwords [@valeriansaliou, e6c5621].
- Dependencies have been bumped to latest versions (namely:
rocksdb,radix,hashbrown,whatlang) [@valeriansaliou].
- Added a release script, with cross-compilation capabilities (currently for the
x86_64architecture, dynamically linked against GNU libraries) [@valeriansaliou, 961bab9].
- RocksDB compression algorithm has been changed from LZ4 to Zstandard, for a slightly better compression ratio, and much better read/write performance; this will be used for new SST files only [@valeriansaliou, cd4cdfb].
- Dependencies have been bumped to latest versions (namely:
rocksdb) [@valeriansaliou, cd4cdfb].
- Fixed a regression on optional configuration values not working anymore, due to an issue in the environment variable reading system introduced in
v1.2.1[@valeriansaliou, #155].
- Optimized some aspects of FST consolidation and pending operations management [@valeriansaliou, #156].
- FST graph consolidation is now able to ignore new words when the graph is over configured limits, which are set with the new
store.fst.graph.max_sizeandstore.fst.graph.max_wordsconfiguration variables [@valeriansaliou, 53db9c1]. - An integration testing infrastructure has been added to the Sonic automated test suite [@vilunov, #154].
- Configuration values can now be sourced from environment variables, using the
${env.VARIABLE}syntax inconfig.cfg[@perzanko, #148]. - Dependencies have been bumped to latest versions (namely:
rand,radixandhashbrown) [@valeriansaliou, c1b1f54].
- Fixed a rare deadlock occuring when 3 concurrent operations get executed on different threads for the same collection, in the following timely order:
PUSHthenFLUSHBthenPUSH[@valeriansaliou, d96546b].
- Reworked the KV store manager to perform periodic memory flushes to disk, thus reducing startup time [@valeriansaliou, 6713488].
- Stop accepting Sonic Channel commands when shutting down Sonic [@valeriansaliou, #131].
- Introduced a server statistics
INFOcommand to Sonic Channel [@valeriansaliou, #70]. - Added the ability to disable the lexer for a command with the command modifier
LANG(none)[@valeriansaliou, #108]. - Added a backup and restore system for both KV and FST stores, which can be triggered over Sonic Channel with
TRIGGER backupandTRIGGER restore[@valeriansaliou, #5]. - Added the ability to disable KV store WAL (Write-Ahead Log) with the
write_ahead_logoption, which helps limit write wear on heavily loaded SSD-backed servers [@valeriansaliou, #130].
- RocksDB has been bumped to
v5.18.3, which fixes a dead-lock occuring in RocksDB at scale when a compaction task is ran under heavy disk writes (ie. disk flushes). This dead-lock was causing Sonic to stop responding to any command issued for the frozen collection. This dead-lock was due to a bug in RocksDB internals (not originating from Sonic itself) [@baptistejamin, 19c4a10].
- Reworked the
FLUSHBcommand internals, which now use the atomicdelete_range()operation provided by RocksDBv5.18[@valeriansaliou, 660f8b7].
- Added the
LANG(<locale>)command modifier forQUERYandPUSH, that lets a Sonic Channel client force a text locale (instead of letting the lexer system guess the text language) [@valeriansaliou, #75]. - The FST word lookup system, used by the
SUGGESTcommand, now support all scripts via a restricted Unicode range forward scan [@valeriansaliou, #64].
- A store acquire lock has been added to prevent 2 concurrent threads from opening the same collection at the same time [@valeriansaliou, 2628077].
- A superfluous mutex was removed from KV and FST store managers, in an attempt to solve a rare dead-lock occurring on high-traffic Sonic setups in the KV store [@valeriansaliou, 60566d2].
- Reverted changes made in
v1.1.5regarding the open filesrlimit, as this can be set from outside Sonic [@valeriansaliou, f6400c6]. - Added Chinese Traditional stopwords [@dsewnr, #87].
- Improved the way database locking is handled when calling a pool janitor; this prevents potential dead-locks under high load [@valeriansaliou, fa78372].
- Added the
server.limit_open_filesconfiguration variable to allow configuringrlimit[@valeriansaliou].
- Added Kannada stopwords [@dileepbapat].
- The Docker image is now much lighter [@codeflows].
- Automatically adjust
rlimitfor the process to the hard limit allowed by the system (allows opening more FSTs in parallel) [@valeriansaliou].
- Limit the size of words that can hit against the FST graph, as the FST gets slower for long words [@valeriansaliou, #81].
- Rework Sonic Channel buffer management using a VecDeque (Sonic should now work better in harsh network environments) [@valeriansaliou, 1c2b9c8].
- FST graph consolidation locking strategy has been improved even further, based on issues with the previous rework we have noticed at scale in production (now, consolidation locking is done at a lower-priority relative to actual queries and pushes to the index) [@valeriansaliou, #68].
- FST graph consolidation locking strategy has been reworked as to allow queries to be executed lock-free when the FST consolidate task takes a lot of time (previously, queries were being deferred due to an ongoing FST consolidate task) [@valeriansaliou, #68].
- Removed special license clause introduced in
v1.0.2, Sonic is fullMPL 2.0now. [@valeriansaliou]
- Change how buckets are stored in a KV-based collection (nest them in the same RocksDB database; this is much more efficient on setups with a large number of buckets -
v1.1.0is incompatible with thev1.0.0KV database format) [@valeriansaliou].
- Bump
jemallocatorto version0.3[@valeriansaliou].
- Re-license from
MPL 2.0toSOSSL 1.0(Sonic has a special license clause) [@valeriansaliou].
- Added automated benchmarks (can be ran via
cargo bench --features benchmark) [@valeriansaliou]. - Reduced the time to query the search index by 50% via optimizations (in multiple methods, eg. the lexer) [@valeriansaliou].
- Initial Sonic release [@valeriansaliou].
