Matthias J. Sax commented on KAFKA-8828:
----------------------------------------
I was referring to the case, in which you would use
`StreamBuilder.globalKTable()` and then try to get the underlying store of the
table via `init()`.
If you use `StreamBuilder.addGlobalStore` the story you pass via the
`StoreBuilder` should be the store you get returned via in `init()` – if you
say you get a different store back, it's indeed a bug.
> [BC Break] Global store returns a TimestampedKeyValueStore in 2.3
> -----------------------------------------------------------------

> Key: KAFKA-8828
> URL: https://issues.apache.org/jira/browse/KAFKA-8828
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.3.0
> Reporter: Marcos Passos
> Priority: Major
>
> Since 2.3, {{ProcessorContext}} returns a {{TimestampedKeyValueStore}} for
> global stores, which is backward incompatible. This change makes the upgrade
> path a lot painful and involves creating a non-trivial adapter to hide the
> timestamp-related functionality in cases where it is not needed.
