> URL: https://issues.apache.org/jira/browse/KAFKA-9126
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 2.4.0
> Reporter: Matthias J. Sax
> Assignee: Leah Thomas

> In 2.4.0 release, we introduced `StreamJoined` configuration object via KIP-479 (KAFKA-8558). The idea of `StreamJoined` is to be an equivalent to `Materialized` but customized for stream-stream joines, that have two stores (in contrast to the usage of `Materialized` that is used for single-store operators).
> During the KIP discussion, the idea to allow setting the store retention time and enable/disable changelogging for the store was discussed. However, at some point this idea was dropped for unknown reasons (seems it slipped).
> We should consider to extend `StreamJoined` with `withRetentionPeriod()` and `loggingEnabled()`/`loggingDisabled()` methods to get feature parity to `Materialized`.
