KVBench

cloned from tidwall/kvbench

KVBench is a Redis server clone backed by a few different Go databases.

It's intended to be used with the redis-benchmark command to test the performance of various Go databases. It has support for redis pipelining. The redis-benchmark can run as explained here https://github.com/tidwall/kvbench#examples.

This cloned version adds more kv databases and automatic scripts.

Features:

Databases
- badger
- BboltDB
- BoltDB
- buntdb
- LevelDB
- cznic/kv
- rocksdb
- pebble
- pogreb
- nutsdb
- sniper
- map (in-memory) with AOF persistence
- btree (in-memory) with AOF persistence
Option to disable fsync
Compatible with Redis clients
