Summary: Make IQv2 query/store interface type safe
Key: KAFKA-13541
URL: https://issues.apache.org/jira/browse/KAFKA-13541
Project: Kafka
Issue Type: Sub-task
Reporter: Patrick Stuedi
Assignee: Patrick Stuedi
Currently the new IQv2 interface allows applications to query state stores
using subclasses of the Query<V> type. Unfortunately there is currently no way
to check that the template type of the query matches the type of the relevant
store the query is executed on. As a consequence stores have to do a set of
unsafe casts.
This ticket is to explore ways to make the query interface type safe where only
type mismatches are detected at compile time.
