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

Thanks for designers @田凌宇 and @范世丽 contribute the kvrocks logo for us.

Building kvrocks

requirements

  • g++ (required by c++11, version >= 4.8)
  • autoconf automake libtool snappy

Build

NOTE: You should install the snappy first:

# Centos/Redhat
sudo yum install -y epel-release && sudo yum install -y git gcc gcc-c++ make snappy snappy-devel autoconf automake libtool which gtest gtest-devel

# Ubuntu
sudo apt-get install gcc g++ make libsnappy-dev autoconf automake libtool which libgtest-dev

# MACOSX
brew install autoconf automake libtool snappy googletest

It is as simple as:

$ git clone --recursive https://github.com/kvrockslabs/kvrocks.git
$ cd kvrocks
$ make -j4

Running kvrocks

$ ./src/kvrocks -c kvrocks.conf

Running test cases

NOTE: You should install the googletest first

make test

Supported platforms

  • centos 6/7
  • ubuntu
  • macosx

Try kvrocks using Docker

$ docker run -it -p 6666:6666 kvrocks/kvrocks
$ redis-cli -p 6666

127.0.0.1:6666> get a
(nil)

Namespace

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, bgsave, etc…

# add token
127.0.0.1:6666>  namespace add ns1 my_token
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
