> Key: KAFKA-6248
> URL: https://issues.apache.org/jira/browse/KAFKA-6248
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Tim Van Laer
> Priority: Minor
>
> In the current implementation of Kafka Streams, it is not possible to set custom configuration to internal topics (e.g. max.message.bytes, retention.ms...). It would be nice if a developer can set some specific configuration.
> E.g. if you want to store messages bigger than 1MiB in a state store, you have to alter the corresponding changelog topic with a max.message.bytes setting.
> The workaround is to create the 'internal' topics upfront using the correct naming convention so Kafka Streams will use the explicitly defined topics as if they are internal.
> An alternative is to alter the internal topics after the Kafka Streams application is started and has created its internal topics.
