Looking for a lightweight java-compatible in-memory key-value store [closed]

Answer 1

I would recommend to try a Redisson. You will able to use distributed and scalable Map or ConcurrentMap and other (Set, List, Queue, Lock ...) implementations on top of high performance key-value Redis server.

Easy example:

Redisson redisson = Redisson.create();

ConcurrentMap map = redisson.getMap("anyMap");

...

redisson.shutdown();
