This is a cache plugin for Objectify that uses Redis. It can work with a standalone Redis instance or with Google's Google Cloud Memorystore for Redis service.

Initialize your ObjectifyFactory with the RedisMemcacheService:

ObjectifyService.init(
    new ObjectifyFactory(
        new RedisMemcacheService("localhost", 6379)));

If you want more configuration options, you can construct the RedisMemcacheService with a JedisPool instance. See the Jedis documentation for more details.
