Cache and Spring

Question

I want to know about some cache libraries to be used with spring. I want the cache to be centralised distributed as I have multiple servers.This also rules out guava(in-memory cache). Redis/Jedis and Couchbase are two options but with lacking support for java. They need all java objects/beans to be serializable. Guava supports java but is in-process. Redisson seems good but I read that it lacks support and maintenance compared to Jedis.

I want to prevent code changes to a great extent, and thus don't want my beans to implement Serializabe, neither do I want to convert my objects to Json or Strings.

Requests for software recommendations are off-topic folks ... — Stephen C, Nov 02 '16 at 12:51

@StephenC I haven't asked something like please tell me a good download manager, its a cache lib to be used with spring that suits my reqs. — rohanagarwal, Nov 03 '16 at 06:15
@GrzegorzBylica I am shifting from single server to multiple servers, hence in-memory cache needs to be upgraded to centralized or distributed cache. Famous centralized/distributed solutions like couchbase and redis aren't specifically designed for cache storage although they provide these facilities, hence the lacking support. — rohanagarwal, Nov 03 '16 at 06:17

For me your requirements are contrary to each other. You need to choose one of

No serialization of any kind. But that works only for cache in single JVM.
Distributed cache. Data stored outside of application JVM. Possible to many nodes. But that requires serialization of some kind. Be it java serialization, JSON, Arvo, Kryo, Parquet, protocollBuffers.. Data be transfered over the network in serialized form.

No matter what you choose, http://docs.spring.io/spring/docs/current/spring-framework-reference/html/cache.html will help you. It has support for

JDK ConcurrentMap-based Cache
Ehcache-based Cache
Caffeine Cache
Guava Cache
GemFire-based Cache
JSR-107 Cache

Why you believe that Redis/Jedis and Couchbase are lacking support for java? They have very good support, but your objects must be serialized.

For Redis, it is supported as cache abstraction by http://docs.spring.io/spring-data/redis/docs/1.7.4.RELEASE/reference/html/#redis:support:cache-abstraction

Similar project exist for Couchbase https://github.com/couchbaselabs/couchbase-spring-cache

Yes, I missed that. Something which needs to be sent over the network needs to be serialized. — rohanagarwal, Nov 03 '16 at 07:17
