> [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}}.
