Distributed cache for key-value pairs

I'm looking for a distributed cache for key-value pairs with these features -

  1. Persistence to disk
  2. Open Source
  3. Java Interface
  4. Fast read/write with minimum memory utilisation
  5. Easy to add more machines to the database (Horizontally Scalable)

What are the databases that fit the bill?

Solution

  • There are a lot of options that you can make use of.

    Redis - the one you've stated by yourself. Its a distinct process, very fast, key-value for sure, but it's not an "in-memory with your application", I mean that you'll always do a socket I/O in order to go to redis process. Its not written in Java, but it provides a descent Java Driver to work with, moreover there is a spring integration.

    If you want a java based solution consider the following:

    memcached - a distributed cache

    Hazelcast - its a datagrid, its much more than simply key-value store, but you might be interested in this as well.

    Infinispan - folks from JBoss have created this one

    EHCache - a popular distributed cache

    Hope this helps
