rekkles's Introduction

rekkles

rekkles is a high performance no-sql database build on BadgerDB with redis protocol support. It meant to provide a key-value store alternative to redis.

Pure golang implementation, no c/c++ dependency
Compatible with redis protocol, Redis client are supported
Persistent all data to the disk
Better transaction support, ttl support

Install

go get github.com/gushitong/rekkles

rekkles server start options:

rekkles -h
Usage of rekkles:
  -a string
    	auth string
  -b string
    	listen address (default ":6380")
  -d string
    	working dir (default "/tmp/rekkles")
  -v string
    	value log dir (default "/tmp/rekkles")
  -s bool	
        sync all writes to disk. Setting this to false would achieve better performance, but may cause data to be lost. (default true)

Example

start rekkles server:

$ rekkles -d /tmp/araydb -v /tmp/araydb -b :6380
2018/09/29 12:05:53 started server at :6380

connect rekkles with redis-cli:

$ redis-cli -p 6380
127.0.0.1:6380> SET k 1
OK
127.0.0.1:6380> GET k
"1"
127.0.0.1:6380> HSET hash k v
(integer) 1
127.0.0.1:6380> HGET hash k
"v"
127.0.0.1:6380> PING
PONG

This benchmark running on my local mac, rekkles should have better performance on SSD.
