------------------------------
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 ?
