--------------------------------------
Summary: Specify returned errors for various APIs and versions
Key: KAFKA-14439
URL: https://issues.apache.org/jira/browse/KAFKA-14439
Project: Kafka
Issue Type: Task
Reporter: Justine Olshan
Kafka is known for supporting various clients and being compatible across
different versions. But one thing that is a bit unclear is what errors each
response can send.
Knowing what errors can come from each version helps those who implement
clients have a more defined spec for what errors they need to handle. When new
errors are added, it is clearer to the clients that changes need to be made.
It also helps contributors get a better understanding about how clients are
expected to react and potentially find and prevent gaps like the one found in
https://issues.apache.org/jira/browse/KAFKA-14417
I briefly synced offline with [~hachikuji] about this and he suggested maybe
adding values for the error codes in the schema definitions of APIs that
specify the error codes and what versions they are returned on. One idea was
creating some enum type to accomplish this.
