2.4.0

Note: In this release, we have upgraded RocksDB to version 8.1.1. In addition, we have introduced a new storage encoding format that can accommodate 64-bit element count and expiration time in milliseconds. To enable this feature, you must include -DENABLE_NEW_ENCODING=ON during the build process (which is not enabled by default). Once the new encoding is enabled, data stored using the old encoding will remain accessible for reading and writing as usual. However, any new data will be written using the new encoding format.

2.3.0

For this release, we now upgrade the RocksDB to 7.9.2 which will significantly improve the compaction performance. Another to be noticed, Kvrocks cluster mode will persist the cluster nodes' topology in the local file by default, you can disable it in flight by config set persist-cluster-nodes-enable no.

  • Add config for log cleaner by @IoCing in #1171
  • Persist the cluster nodes info after applying the cluster topology by @git-hulk in #1219

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)

Here is a comprehensive list of changes in this release compared to 2.0.3

    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

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

  • Fix SETNX and MSETNX commands can't guarantee atomicity (#337)
  • Fix the replicas won't reconnect when failing to connect with master (#344)
  • Fix master pauses synchronizing with replicas (#347)
  • Fix wrong mater port if enabling master-use-repl-port (#360)

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

  • HSET command supports to set multiple fields (#274)
  • Allow to use host in the master-slave replication (#301)
  • Adapt redis sentinel ping check (#316)

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.

Improvements
