This release provides support for server-assisted, client-side caching, and is currently alpha grade. Currently it is supported on top of the Jedis class, and will be merged to Jedis/UnifiedJedis classes via configuration parameters.
Client-side caching is available through JedisClientSideCache class, with RESP3 only.
Note: The process of ensuring the last invalidation when there is none, is still time consuming; it is suggested to use a smaller socket timeout if this is an issue. We have started with only GET command at this moment.

class CacheExample {
public static void main() {
HostAndPort hnp = HostAndPort.from("localhost:6379");
JedisClientConfig config = DefaultJedisClientConfig.builder()
.resp3() // RESP3 protocol
.socketTimeoutMillis(20) // smaller socket timeout
.password("foobared")
.build();
JedisClientSideCache jCache = new JedisClientSideCache(hnp, config);
jCache.set("foo", "bar");
jCache.get("foo");
jCache.get("foo"); // cache hit
jCache.del("foo");
jCache.close();
}
