Show HN: Keybench – Scriptable, extensible performance tool for key value stores

https://github.com/guycipher/keybench
7•alexpadula•2h ago
I've been working with storage engines for quite a while and really there was no similar tool to sysbench and or HammerDB for key-value storage engines. Thus I introduce a POC called keybench. I hope you check it out, and do give it a run to drive your favorite engine.

Cheers!
