----------------------------------
Summary: queryMetadataForKey
Key: KAFKA-14070
URL: https://issues.apache.org/jira/browse/KAFKA-14070
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 3.2.0
Reporter: Balaji Rao
When using key-value state stores with Processor API, one can add key-value
state stores of arbitrary key types. This could lead to the method
`queryMetadataForKey` in `KafkaStreams` to be used with incorrect expectations.
In my understanding, `queryMetadataForKey` uses the source topics of the
processor connected to the store to return the `KeyQueryMetadata`. This means
that it could provide "incorrect" answers when used with key-value stores of
arbitrary key types. The description of the method should be improved to make
users aware of this pitfall.
