             Summary: Convert Kafka RPCs to use automatically generated code
                 Key: KAFKA-7830
                 URL: https://issues.apache.org/jira/browse/KAFKA-7830
             Project: Kafka
          Issue Type: Improvement
          Components: clients, core
            Reporter: Colin P. McCabe
            Assignee: Colin P. McCabe


KAFKA-7609 added a way of automatically generating code for reading and writing 
Kafka RPC message types from JSON schemas.

Automatically generated code is preferrable to manually written serialization 
code. 

* * It is less tedious and error-prone to use than hand-written code.
* For developers writing Kafka clients in other languages, the JSON schemas are 
useful in a way that the java serialization code is not.
* It will eventually be possible to automatically validate aspects of 
cross-version compatibility, when using JSON message schemas.
* Once all of the RPCs are converted, we can drop using Structs in favor of 
serializing directly to ByteBuffer, to reduce GC load.

This JIRA tracks converting the current hand-written message serialization code 
to automatically generated serialization.
