--------------------------------------
Summary: Extend `StreamJoined` to allow more store configs
Key: KAFKA-9126
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
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 not unknown reasons (seems it slipped).
We should consider to extend `StreamJoined` with `withRetentionPeriod()` and
`loggingEnabled()`/`loggingDisabled()` methods to get feature parity to
`Materialized`.
