async connection pool

I am exploring concept of using in Async Connection pool and wondering is that right approach, since lettuce inherantly supports pipelining?

Actually, pooling is only required when using transactions or blocking operations (BLPOP, XREAD … BLOCK …). In all other cases, you're better off with a single connection.

Thanks Mark for immediate response!!
In that case, I do better off using sync connection pooling for the blocking operations.

Note that blocking redis operations are a different kind of blocking than Java blocking (synchronous) calls.

Mark,
Please elaborate more about your last statement.

Moreover I tried the example to create connection pool using cluster as per the documentation
https://lettuce.io/core/release/reference/#connection-pooling.blocking
https://github.com/lettuce-io/lettuce-core/wiki/Connection-Pooling

GenericObjectPool<StatefulRedisClusterConnection<String, String>> pool = ConnectionPoolSupport
               .createGenericObjectPool(() -> clusterClient.connect(), new GenericObjectPoolConfig());

but it gives following error.
