Status

Current state: Adopted (2.1.0)

Discussion thread: TBD

JIRA:

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

StoreBuilder initializes itself as caching disabled, and only expose a withCachingEnabled() to flip this config via code. However, it does not provide a withCachingDisabled() function to allow users to flip it back, and hence restricting certain optimization opportunities (see KAFKA-6998 for details).

Public Interfaces

public interface StoreBuilder<T extends StateStore> {


    /**
     * Disable caching on the store.
     * @return  this
     */
    StoreBuilder<T> withCachingDisabled();
}

Proposed Changes

As above.

Compatibility, Deprecation, and Migration Plan

• There should be very minor compatibility issues since very rarely a user would extend the StoreBuilder interface themselves.

Rejected Alternatives

None.
