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)
