dongjinleekr commented on pull request #8117: KAFKA-8403: Suppress needs a
Materialized variant
URL: https://github.com/apache/kafka/pull/8117
This is a completely new implemetation from the previous PR.
- [KAFKA-8403: Suppress needs a Materialized
variant](https://issues.apache.org/jira/browse/KAFKA-8403)
- [KIP-508: Make Suppression State
Queriable](https://cwiki.apache.org/confluence/display/KAFKA/KIP-508%3A+Make+Suppression+State+Queriable)
Here are some guidelines:
- 9bd279f ~ 37060b6: Refactor the `TimeOrderedKeyValueStore` into new
interfaces, with separating `Serdes` from BytesStore. (see
`MeteredSuppressionBuffer`)
- 798af5c ~ 0a684e0: Implement the `KTable#suppress` variant and make it
queriable.
- 8f2e2c8 ~ 3387e27: Make `SuppressionBuffer` accessable by the users.
- 821014f: Implement a testing functionality.
Please have a look when you are free. Thanks in advance! :smile:

> WIP KIP:

> The newly added KTable Suppress operator lacks a Materialized variant, which
> would be useful if you wanted to query the results of the suppression.
> Suppression results will eventually match the upstream results, but the
> intermediate distinction may be meaningful for some applications. For
> example, you could want to query only the final results of a windowed
> aggregation.
