Support for Local Cache Eviction Policy

[atharva29]

Expected behavior

Please add support of TTL, Max Idle , Eviction Policy support to redis server assisted client side caching.
This will reduce the memory requirement on Application's side.

https://github.com/redisson/redisson-examples/blob/master/collections-examples/src/main/java/org/redisson/example/collections/LocalCachedMapExamples.java#L46

        .maxIdle(Duration.ofSeconds(60))
        .timeToLive(Duration.ofSeconds(60))
        .evictionPolicy(EvictionPolicy.LFU)
        .syncStrategy(SyncStrategy.UPDATE)

@atharva29 Thank you for sharing this feature request.

Could you please edit your post and add the Jedis version for future reference? Thanks again.

hi @atharva29 ,
We will evaluate your request and try to see how we can improve CSC with considerations on memory.
Having said that, with the latest enhancements in CSC, we now support custom EvictionPolicy implementations, along with additional options that provide more control for consumer applications. For memory management, you can configure the maxSize and cacheable properties to see how they can benefit your use case.

Here’s an example of how you can set it up:

    AllowAndDenyListWithStringKeys cacheable = 
        new AllowAndDenyListWithStringKeys(null, null, Collections.singleton("foo"), null);
    EvictionPolicy myPolicy = new MyCustomEvictionPolicy();
    CacheConfig.builder().evictionPolicy(myPolicy).maxSize(1000).cacheable(cacheable).build();

let us know if it works for you..
