I'm seeing a lot in kafka logs with Shrinking and Expanding ISR for partition [TOPIC].
Causing some of the brokers (and partitions) unavailable to producer and consumer clients.
I'm now looking at these configs
Should I set these to higher value? What is the best value for these param?
Help is really appreciated. Thanks!
You have to see this
|ISR shrink rate||kafka.server:type=ReplicaManager,name=IsrShrinksPerSec||If a broker goes down, ISR for some of the partitions will shrink. When that broker is up again, ISR will be expanded once the replicas are fully caught up. Other than that, the expected value for both ISR shrink rate and expansion rate is 0.|
