Apache Kvrocks(Incubating) is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol. Kvrocks intends to decrease the cost of memory and increase the capacity 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
  • Cluster mode, centralized management but compatible with Redis cluster client access

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

Build and Run kvrocks


# CentOS / RedHat
sudo yum install -y epel-release
sudo yum install -y git gcc gcc-c++ make cmake autoconf automake libtool libstdc++-static python3 which openssl-devel

# Ubuntu / Debian
sudo apt update
sudo apt install -y git gcc g++ make cmake autoconf automake libtool python3 libssl-dev

# macOS
brew install autoconf automake libtool cmake openssl

# Please force linking the openssl if still can't find after installing openssl
brew link --force openssl


It is as simple as:

$ git clone https://github.com/apache/incubator-kvrocks.git
$ cd incubator-kvrocks
$ ./x.py build # `./x.py build -h` to check more options;
               # especially, `./x.py build --ghproxy` will fetch dependencies via ghproxy.com.

To build with TLS support, you'll need OpenSSL development libraries (e.g. libssl-dev on Debian/Ubuntu) and run:

$ ./x.py build -DENABLE_OPENSSL=ON

To build with luaJIT instead of lua for better performance, run:

$ ./x.py build -DUSE_LUAJIT=ON

Running kvrocks

$ ./build/kvrocks -c kvrocks.conf

Running kvrocks using Docker

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

Connect kvrocks service

$ redis-cli -p 6666> get a

Running test cases

$ ./x.py build --unittest
$ cd build
$ ./unittest

Supported platforms

  • Linux distributions
    • CentOS
    • Ubuntu
    • and most other distros
  • macOS


Namespace is used to isolate data between users. Unlike all the Redis databases can be visited by requirepass, we use one token per namespace. requirepass is regraded as admin token, and only admin token allows to access the namespace command, as well as some commands like config, slaveof, bgsave, etc..

# add token>  namespace add ns1 my_token

# update token> namespace set ns1 new_token

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

# delete namespace> namespace del ns1


Kvrocks implements a proxyless centralized cluster solution but its accessing method is completely compatible with the Redis cluster client. You can use Redis cluster SDKs to access the kvrocks cluster. More details, please see: Kvrocks Cluster Introduction
