-----------------------------
Resolution: Fixed
> Reduce Kafka Streams Footprint
> ------------------------------
>
> Key: KAFKA-6761
> URL: https://issues.apache.org/jira/browse/KAFKA-6761
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Bill Bejeck
> Assignee: Bill Bejeck
> Priority: Major
> Fix For: 2.1.0
>
>
> The persistent storage footprint of a Kafka Streams application contains the
> following aspects:
> # The internal topics created on the Kafka cluster side.
> # The materialized state stores on the Kafka Streams application instances
> side.
> There have been some questions about reducing these footprints, especially
> since many of them are not necessary. For example, there are redundant
> internal topics, as well as unnecessary state stores that takes up space but
> also affect performance. When people are pushing Streams to production with
> high traffic, this issue would be more common and severe. Reducing the
> footprint of Streams have clear benefits for reducing resource utilization of
> Kafka Streams applications, and also not creating pressure on broker's
> capacities.
