Summary: 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
Fix For: 1.2.0
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 of Kafka Streams operations, and also for KSQL deployment
resource utilization
