--------------------------------------
Summary: Provide a configuration to control consumer max in-flight
fetches
Key: KAFKA-4133
URL: https://issues.apache.org/jira/browse/KAFKA-4133
Project: Kafka
Issue Type: Improvement
Components: consumer
Reporter: Jason Gustafson
With KIP-74, we now have a good way to limit the size of fetch responses, but
it may still be difficult for users to control overall memory since the
consumer will send fetches in parallel to all the brokers which own partitions
that it is subscribed to. To give users finer control, it might make sense to
add a `max.in.flight.fetches` setting to limit the total number of concurrent
fetches at any time. This would require a KIP since it's a new configuration.
