----------------------------------------
Summary: Make serializer classes final
Key: KAFKA-4424
URL: https://issues.apache.org/jira/browse/KAFKA-4424
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Matthias Bechtold
Priority: Minor
Implementations of simple serializers / deserializers should be final to
prevent JVM method call overhead.
See also:

This breaks the API slightly, inheritors must change to generic interfaces
Serializer / Deserializer. But architecture-wise final serialization classes
make the most sense to me.
So what do you think?
