Redisより早いとかいうKeyDBを試してみた!

KeyDBとかいうRedisの代わりになりそうな面白そうなものを見つけたので試してみる。

docs: https://keydb.dev/
github: https://github.com/JohnSully/KeyDB

Redisのforkとだけいうあって、使い勝手は普通のRedisと変わらない使い方ができるそう。Forkしたことによってより迅速な開発が可能になったのだとか。

計測

性能計測にはredis-benchmarkを使用

参考: http://mogile.web.fc2.com/redis/redis409/topics/benchmarks.html

redis-benchmark --csv -r 6

KeyDBはDockerも用意してあるようなので、RedisもDockerで用意することにした。

docker run -p 6379:6379 -d eqalpha/keydb # KeyDB
docker run -p 6379:6379 -d redis # redis

結果

KeyDB

redisの方が性能いいじゃねえかどうなってんだ...
