KeyDB is a fork of Redis. KeyDB project claims that the Redis implementation approach is not correct and can be better, in terms of performance.
KeyDB is a high performance open source database used at Snap, and a powerful drop-in alternative to Redis. While many databases keep the best features locked in their paid offerings, KeyDB remains fully open source. This best enables Snap & the community to collaborate and benefit together in the projects development.
We also have to keep in mind that KeyDB has a great feature that Redis doesn’t have (at least in their Open-Source version) like:
The “On Flash” feature. This feature uses SSD disks as an extension of RAM, spending less RAM with very similar performance.
