Matthias J. Sax updated KAFKA-16458:
------------------------------------
Labels: needs-kip (was: )
> Add contains method in KeyValue store interface
> -----------------------------------------------
>
> Key: KAFKA-16458
> URL: https://issues.apache.org/jira/browse/KAFKA-16458
> Project: Kafka
> Issue Type: Wish
> Components: streams
> Reporter: Ayoub Omari
> Priority: Minor
> Labels: needs-kip
>
> In some stream processors, we sometimes just want to check if a key exists in
> the state store or not.
>
> I find calling .get() and checking if the return value is null a little bit
> verbose
> {code:java}
> if (store.get(key) != null) {
> }{code}
>
> But I am not sure if it is on purpose that we would like to keep the store
> interface simple.
