Class UUIDDeserializer

java.lang.Object

org.apache.kafka.common.serialization.UUIDDeserializer

All Implemented Interfaces:

Closeable, AutoCloseable, Deserializer<UUID>

public class UUIDDeserializer
extends Object
implements Deserializer<UUID>

We are converting the byte array to String before deserializing to UUID. String encoding defaults to UTF8 and can be customized by setting the property key.deserializer.encoding, value.deserializer.encoding or deserializer.encoding. The first two take precedence over the last.
