Answer 1

You have two options:

1. You perform serialization (JDK serialization, JSON, Protobuf, ...) on your own. You can do that before sending data to Redis, or you implement an own RedisCodec that does the job (see CustomCodecTest.java or CustomCodecTest.java)
2. Use a framework in front of lettuce (such as Spring Data Redis). Spring Data Redis comes with various codecs that provide serialization out of the box.
