yazgoo created KAFKA-10413:
------------------------------

             Summary: rebalancing leads to unevenly balanced connectors
                 Key: KAFKA-10413
                 URL: https://issues.apache.org/jira/browse/KAFKA-10413
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 2.5.1
            Reporter: yazgoo


Hi,

With CP 5.5, running kafka connect s3 sink on EC2 whith autoscaling enabled, if a connect instance disappear, or a new one appear, we're seeing unbalanced consumption, much like mentionned in this post:

[https://stackoverflow.com/questions/58644622/incremental-cooperative-rebalancing-leads-to-unevenly-balanced-connectors]


This usually leads to one kafka connect instance taking most of the load and consumption not being able to keep on.
Currently, we're "fixing" this by deleting the connector and re-creating it, but this is far from ideal.

Any suggestion on what we could do to mitigate this ?
