+ enables you to provide topic configuration parameters for any topics created by Kafka Streams.
+ This includes repartition and changelog topics.
+ You can provide the configs via the <code>StreamsConfig</code> by adding the configs with the prefix as defined by <code>StreamsConfig#topicPrefix(String)</code>.
+ Any properties in the <code>StreamsConfig</code> with the prefix will be applied when creating internal topics.
+ Any configs that aren't topic configs will be ignored.
+ If you already use <code>StateStoreSupplier</code> or <code>Materialized</code> to provide configs for changelogs, then they will take precedence over those supplied in the config.
