kvrocks is an open-source key-value database. which is based on rocksdb and compatible with Redis protocol. Intention to decrease the cost of memory and increase the capability while compared to Redis. The design of replication and storage was inspired by rocksplicator and blackwidow.

kvrocks has the following key features:

  • Redis protocol, user can use redis client to visit the kvrocks
  • Namespace, similar to redis db but use token per namespace
  • Replication, async replication using binlog like MySQL
  • High Available, supports redis sentinel to failover when master or slave was failed
  • Codis Protocol, the user can use the codis proxy and dashboard to manage the kvrocks

Thanks for @smartlee and the trip.com designer(@范世丽) contributes the kvrocks logo for us

Namspace

namespace was used to isolate data between users. unlike all the redis databases can be visited by requirepass, we use one token per namespace. requirepass was regraded as admin token, only admin token allows to access the namespace command, as well as some commands like config, slaveof, bgave, etc…

# add token
127.0.0.1:6666>  namespace add ns1 mytoken
OK

# update token
127.0.0.1:6666> namespace set ns1 new_token
OK

# list namespace
127.0.0.1:6666> namespace get *
1) "ns1"
2) "new_token"
3) "__namespace"
4) "foobared"

# delete namespace
127.0.0.1:6666> namespace del ns1
OK
