我试用了一个声称比 Redis 更快的 KeyDB！

我发现了一个叫做KeyDB的有趣替代Redis的东西，所以我想试试看。

文档：https://keydb.dev/
GitHub：https://github.com/JohnSully/KeyDB

据说，仅仅提到Redis的fork，它的使用方式与普通的Redis没有什么区别。据说通过进行fork，使得更快速的开发成为可能。

测量

用于性能测量的工具是redis-benchmark。

请参考以下链接：http://mogile.web.fc2.com/redis/redis409/topics/benchmarks.html

redis-benchmark --csv -r 6

由于KeyDB也提供了Docker，所以我决定使用Docker准备Redis。

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

结果 –

$ redis-benchmark --csv -r 6

redis的性能比较好吧，怎么回事啊…
