`Topology#addGlobalStore` takes any `StoreBuilder`, but `InternalTopologyBuilder#addGlobalStore` restricts it to `StoreBuilder<KeyValueStore>`. This PR relaxes the restriction in `InternalTopologyBuilder#addGlobalStore` to match `Topology#addGlobalStore`.
Testing: adds a new unit test to show that a StoreBuilder<WindowStore> can be used in InternalTopologyBuilder#addGlobalStore. This required creating two new mocks, `MockWindowStore` and `MockWindowStoreBuilder`, modelled on `MockKeyValueStore` and `MockKeyValueStoreBuilder`, respectively. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) [ Full content available at: https://github.com/apache/kafka/pull/5725 ] This message was relayed via gitbox.apache.org for [email protected]
