---------------------------------------------------------------------------
[~sagarrao] do you think you'll be able to get in a fix for this in the next
few weeks? It would be good to have this working in full capacity by 3.0
(I wouldn't consider it a blocker for 3.0, but we have enough time before code
freeze that this should not be an issue, provided someone can pick it up)

> Project: Kafka

> Reporter: Michael Viamari
> Priority: Major

>
> [KIP-614|https://cwiki.apache.org/confluence/display/KAFKA/KIP-614%3A+Add+Prefix+Scan+support+for+State+Stores]
> and [KAFKA-10648|https://issues.apache.org/jira/browse/KAFKA-10648]
> introduced support for {{prefixScan}} to StateStores.
> It seems that many of the intermediate {{StateStore}} interfaces are missing
> a definition for {{prefixScan}}, and as such is not accessible in all cases.
> For example, when accessing the state stores through a the processor context,
> the {{KeyValueStoreReadWriteDecorator}} and associated interfaces do not
> define {{prefixScan}} and it falls back to the default implementation in
> {{KeyValueStore}}, which throws {{UnsupportedOperationException}}.
