Five Apache projects you probably didn't know about

Another under the radar Apache project I've found myself using is Apache KvRocks

It's a Redis compatible database on top of RocksDB, so unlike Redis it uses the disk instead of RAM, but you can control how much data is cached in RAM, obviously Kvrocks will be slower than Redis for uncached data.

Useful in situations where you want a KV data store that isn't limited by your memory specs but is compatible with everything that speaks Redis.

I've used this one too. It works well.

Cool. This post is right beside the 37signals one[1] that mentions SolidCache[0] "A database-backed ActiveSupport::Cache::Store".

I discovered two solutions in one day.

The advantage with kvrocks is that it supports the Redis protocol, so you can use all the drivers, tools, cluster tools for Redis.

I'm using Apache Ratis (and Nifi) for a side project. It's a nice Raft implementation that's actively used and maintained:
