-----------------------------------
Summary: Limit the length of the `reason` field sent on the wire
Key: KAFKA-14013
URL: https://issues.apache.org/jira/browse/KAFKA-14013
Project: Kafka
Issue Type: Improvement
Reporter: David Jacot
Assignee: David Jacot
KIP-800 added the `reason` field to the JoinGroupRequest and the
LeaveGroupRequest as I mean to provide more information to the group
coordinator. In https://issues.apache.org/jira/browse/KAFKA-13998, we
discovered that the size of the field is limited to 32767 chars by our
serialization mechanism. At the moment, the field either provided directly by
the user or constructed internally is directly set regardless of its length.
Given the purpose of this field, it seems acceptable to only sent the first 255
chars on the wire. That would prevent us from hitting that limit again while
ensuring that the amount of bytes sent to the broker remain within an
acceptable range.
We should apply this to the JoinGroupRequest and to the LeaveGroupRequest.
