dajac commented on pull request #7829: KAFKA-9297; CreateTopic API do not work
with older version of the request/response
URL: https://github.com/apache/kafka/pull/7829
The create topic api do not work with older version of the api. It can be
reproduced by trying to create a topic with `kafka-topics.sh` from 2.3. It
timeouts.
The latest version of the response has introduced new fields with default
values. When those fields are not supported by the version used by the client,
the serialisation mechanism expect to have the default values and throw
otherwise. The current implementation in KafkaApis set them regardless of the
version used.
It seems that it has been introduced in KIP-525.
