Kafka protocol CreateAcls message
Request versions summary:
- Version 0 was removed in Apache Kafka 4.0, Version 1 is the new baseline.
Version 1 adds resource pattern type.
Version 2 enables flexible versions.
Version 3 adds user resource type.
Response versions summary:
- Version 0 was removed in Apache Kafka 4.0, Version 1 is the new baseline.
Starting in version 1, on quota violation, brokers send out responses before throttling.
Version 2 enables flexible versions.
Version 3 adds user resource type.
