We use it for a year now in production and so far so good. We couldn't handle anymore having huge instances with a lot of RAM to hold data in Redis.

It looks like a normal database to me: disk storage for most of the data, and some cache in memory to speed up read queries. Everything is customizable.

I'm still waiting for a nice way to deploy it in a Kubernetes cluster, like a Helm Chart to easily setup a cluster with primaries and replicas. Also, the lack of keys eviction like LRU is problematic for us in some cases, it would be a nice addition.

I’ve been testing kvrocks as a replacement for a Scylla use case where we have TBs of data and uniform TTLs. In many of these LSM dbs, compaction is the thing that really kills throughput, making TTLs (or really any updates/deletes) difficult.

KVRocks doesn’t expose it directly right now so it requires code changes, but so far I have had good success with FIFO compaction. When an sstable gets old enough, it just gets dropped.
