Summary: Support Read Only Kafka Topics / Clusters
Key: KAFKA-10187
URL: https://issues.apache.org/jira/browse/KAFKA-10187
Project: Kafka
Issue Type: New Feature
Components: core
Reporter: Manish Maheshwari
Request to support Read Only Kafka Topics / Read Only Kafka Clusters.
The reason so put a topic / cluster in read only mode is for deployments with
load balanced multiple Kafka clusters where when a single cluster has to be
taken out for maintenance, we want the ingest of new data into these topics /
clusters to stop for some time. Consumption should still continue to allow
consumers to catch up (including MM2 to replicate the data). With ingestion
stopped we can be relatively certain that consumers will catch up in a
controlled duration to then take the cluster out for maintenance.
Alternate workarounds exist by modifying LB configuration but they are not
elegant and need a LB restart. We can also potentially enable firewalls on the
host to block producer IP's but thats also not a clean solution.
Thoughts?
