------------------------------------
Resolution: Not A Bug
> Kafka streams repartitioning topic settings crashing multiple nodes
> -------------------------------------------------------------------
>
> Key: KAFKA-8201
> URL: https://issues.apache.org/jira/browse/KAFKA-8201
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.0.0
> Reporter: Anders Aagaard
> Priority: Major
>
> We had an incident in a setup using kafka streams version 2.0.0 and kafka
> version 2.0.0 protocol version 2.0-IV1. The reason for it is a combination of
> kafka streams defaults and a bug in kafka.
> Info about the setup: Streams application reading a log compacted input
> topic, and performing a groupby operation requiring repartitioning.
> Kafka streams automatically creates a repartitioning topic with 24 partitions
> and the following options:
> segment.bytes=52428800, retention.ms=9223372036854775807,
> segment.index.bytes=52428800, cleanup.policy=delete, segment.ms=600000.
>
> This should mean we roll out a new segment when the active one reaches 50mb
> or is older than 10 mniutes. However, the different timestamps coming into
> the topic due to log compaction (sometimes varying in multiple days) means
> the server will see a message which is older than segments.ms and
> automatically trigger a new segment roll out. This causes a segment
> explosion. Where new segments are continuously rolled out.
> There seems to be a bug report for this server side here :
> https://issues.apache.org/jira/browse/KAFKA-4336.
> This effectively took down several nodes and a broker in our cluster.
