    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
>  # 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.
