Enhanced Client-side caching

We are happy to announce that improved server-assisted, client-side caching is now generally available! Special thanks to all our beta testers for their valuable feedback, which helped us refine and improve the initial implementation.

Client-side caching is supported exclusively with the RESP3 protocol with Redis >= 7.4 and is available in UnifiedJedis, JedisPooled, and JedisCluster and other classes.

How to try Client-Side Caching

1. Install Jedis 5.2.0
2. Use the following code example to get started:

public class CSCExampleTest {
  public static void main() {
HostAndPort node = HostAndPort.from("localhost:6379");
JedisClientConfig clientConfig = DefaultJedisClientConfig.builder()
    .resp3()                // RESP3 protocol is required for client-side caching
    //.user("myuser")       // Redis server username (optional)
    //.password("mypass")   // Redis user's password (optional)
    .build();
CacheConfig cacheConfig = getCacheConfig();
Cache cache = CacheFactory.getCache(cacheConfig);
try (UnifiedJedis client = new UnifiedJedis(node, clientConfig, cache)) {
client.set("foo", "bar");
client.get("foo");
client.get("foo"); // Cache hit
System.out.println("Cache size: " + cache.getSize()); // 1
System.out.println(cache.getStats().toString());
//Let's change the value of "foo" to invalidate the value stored in the local cache
client.mset("foo", "new_value", "ignore_me:1", "another_value");
Thread.sleep(1000); // wait for the cache invalidation to happen
System.out.println(client.get("foo")); // Cache miss
System.out.println(cache.getStats().toString());
client.get("ignore_me:1"); // Client will ignore this key
System.out.println("Cache size: " + cache.getSize()); // still 1
// check the cache stats
System.out.println(cache.getStats().toString());
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
