Others
2.0.6
Thanks ChrisZMF who implements slot-based data migration for Kvrocks cluster
mode, this authentically makes kvrocks cluster scalable. Even though it already is
used in production environments, you still should be cautious of it.
Here is a comprehensive list of changes in this release compared to 2.0.5
New features
- Support slot-based data migration (#430)
Biggest feature of this version, authentically makes kvrocks scalable,
user can use CLUSTERX MIGRATE command to migrate slot and use CLUSTERX
SETSLOT to change cluster slot distribution after finishing migration. - Make level0_file_num_compaction_trigger of RocksDB configurable (#455)
- Support CLUSTERX SETSLOT command (#463)
Improvements
- Support executing INFO command during restoring database (#375)
- Auto Rewrite the config after the namespace was updated (#423)
- Support to convert sortedint type to zset type in kvrocks2redis (#431)
- Optimize the seek of RocksDB iterators (#438)
- Make the bitmap range the same with that of Redis (#465)
- Support GET command on bitmap type (#447)
- Support to use row cache of RocksDB (#407)
Bug fixes
- Fix the parameter blob_garbage_collection_age_cutoff would be always zero (#425)
- Fix config rewrite overwrite the first rename-command with the last one (#429)
- Fix zrevrangebyscore for multi members with the same max score (#434)
- Fix data race in SetCurrentConnection (#440)
- Fix failing full replication when enabling slave-empty-db-before-fullsync (#446)
- Fix memory leak when full replication (#461)
Maybe leak dozen kilobytes per full replication - Fix the bitmap range is smaller than that of Redis (#465)
2.0.5
Here is a comprehensive list of changes in this release compared to 2.0.4
New features
-
Implement zrevrangebylex command (#381)
-
Use some rocksdb new feature (#395)
- Support blob db (key-value separation) which requires RocksDB version greater than 6.18
- Enable partitioned index/filter for SST and hash index for data block
- Enable whole key filter for memtable
- Remove dynamic resize block and SST
- Only apply compression to SST which level is more than 2
Please note that, if your rocksdb version is lower than 6.6.0, it can't reload the data of new version,
you should update cautiously. -
Implement CAS and CAD commands for string type (#415)
-
Support to use row cache of RocksDB (#407)
Improvements
- Add rocksdb ops statistics into the info command (#387)
These statistics can more truly reflect the load of rocksdb. - Add the maxclients to the info command output (#391)
- Add write stall/stop stats to info command output (#396)
- Make kvrocks2redis work (#404)
- Adjust the max open file limit according to the max clients and
rocksdb max open files (#418)

2.0.4
Here is a comprehensive list of changes in this release compared to 2.0.3
New features
- Support LUA script commands (#363) (#369)
Currently, support EVAL, EVALSHA, and SCRIPT commands, but SCRIPT KILL
and DEBUG subcommands are not supported.
Improvements
- Allow metadata and subkey CF to share a single block cache (#365) (#373)
- Add master_repl_offset in INFO command output (#374)
Bugfixes
- Fixed dynamic resize target_file_size_base bug (#368)
Before we only apply this strategy to the default CF(i.e. subkey CF)
2.0.3
If your kvrocks instances are 2.0.2 and use redis-sentinel to implement HA, you should
upgrade urgently, please see #352 for details.
Here is a comprehensive list of changes in this release compared to 2.0.2
Improvements
- Use the rocksdb MultiGet interface in the MGET command (#331)
- Avoid useless space allocation in SetBit (#338)
- Auto set master/replica replication by cluster topology (#356)
- Support client kill type subcommands to adapt redis-sentinel (#352) (#361)
From 2.0.2, we support MULTI-EXEC, but don't support client kill type $type,
so MULTI-EXEC will be rollbacked when failing to parse unknown kill type
in client command, and cause redis-sentinel fails to failover.
Bugfixes
2.0.2
We design new cluster solution for kvrocks, but it is experimental, don't recommend
to deploy in production environments. And because in cluster mode, to be efficient to
migrate keys based on slot when scale, we encode key with slot id, but in order to be
compatible with the old version, we don't do that in standalone mode, so data is not
compatible between standalone mode with cluster mode, you must migrate data if
you want to change mode, otherwise, kvrocks will make data corrupt.
In order to better support the cluster mode, we are developing a meta server to
manage kvrocks cluster, coming soon!
Here is a comprehensive list of changes in this release compared to 2.0.1
New features
- Support rename command in config file (#272)
- Support transaction (#285)
Support MULTI, EXEC, DISCARD command, but don't support
WATCH and UNWATCH commands. - Support the auto-resize-block-and-sst config directive (#289)
- Support to resize rocksdb.block_size automatically (#294)
- Support cluster mode (#302)
Similar with redis cluster mode, but use CLUSTERX command to set
cluster topology (#324).
Data encoding changes
- Encode key with slot id (#291) (#330)
In cluster mode, to be efficient to migrate keys by slot when scale,
we encode key with slot id, but in standalone mode, we don't. That is
to say, data is not compatible between standalone mode with cluster mode,
you must migrate data if you want to change mode, otherwise, kvrocks
will make data corrupt.
Bug fixes
- Set TCP_KEEPALIVE for replication connection (#284)
Replicas can handle network failure with master, before this commit,
network failure may result in unrecoverable replication interrupt. - Fix ZSET can't add the same member with different scores (#298)
- Make CONFIG SET command thread safe (#310)
- Fix LTRIM only delete first item, LREM can't correctly remove
repeated items (#314)
Improvements
2.0.1
Here is a comprehensive list of changes in this release compared to 2.0.0
New features

Bug fixes
- Fix uninitialized Rocksdb.level0_stop_writes_trigger (#236)
- Fix condition race for ReclaimOldDBPtr (#246)
- Fix data race for accessing database in some commands (#253) (#261)
In spop, zremrangebylex, zremrangebyscore commands, the lock guard
for accessing the database may not work actually. - Fix returning wrong string range in GETRANGE command (#254)
- Fix skipping wrong CURRENT file when full synchronization (#260)
Resuming broken transfer based files may be not available if replicas
skip transferred wrong CURRENT file of RocksDB.

2.0.0
Kvrocks 2.0 brings some new useful features that solve actual problems in
the production environment. Please note that this version instance still
can replicate from old version master but old version replicas can't replicate
new version master. Otherwise, we start to use new logo, thanks @tianlingyu1997
Here is a comprehensive list of changes in this release compared to 1.3.2
New features
- Don't use extra port for replication (#200)
- Use checkpoint to implement data snapshot when full replication (#208)
Reduce disk space and bandwidth usage and decrease the time of replicas
recovery during full synchronization. - Use checkpoint to implement kvrocks backup (#232)
- Replicas can empty db before fullsync (#233)
Replicas use less disks space if enabled, but have a risk to lose data.
Command changes
- Add QPS and input/output kbps for INFO command (#213)
- Add pubsub_patterns for INFO command (#234)
- Slowlog omits args or argument string if too many or big (#215)
Cluster
- Remove codis support (#217)
From now, we doesn't support codis, you can adopt pre-sharding to
implement cluster, and we are developing new cluster solution that is
similar with redis cluster mode, please see #219.
Bugfixes
- Fix kvrocks can't auto resume after no space error (#229)
Dependencies
- Upgrade rocksdb to latest tag v6.19.3 (#226)
