Sagar Rao commented on KAFKA-12925:
-----------------------------------
Thanks [~mviamari] .
[~mjsax]/[~ableegoldman]: I have created a PR with the implementations for the
remaining classes. Now, only 2 test classes are missing namely
GenericInMemoryKeyValueStore and GenericInMemoryTimestampedKeyValueStore. For
them, it will be difficult to add the implementation. Plz review.
> prefixScan missing from intermediate interfaces

> [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}}.
