------------------------------------
Resolution: Fixed
> Client support for OffsetFetch and OffsetCommit with topic ID
> -------------------------------------------------------------
>
> Key: KAFKA-15283
> URL: https://issues.apache.org/jira/browse/KAFKA-15283
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, consumer
> Reporter: Kirk True
> Assignee: Lan Ding
> Priority: Critical
> Labels: kip-848-client-support, newbie, offset
> Fix For: 4.2.0
>
>
> Currently, {{KafkaConsumer}} keeps track of topic IDs in the in-memory
> {{ConsumerMetadata}} object, and they are provided to the {{FETCH}} and
> {{METADATA}} RPC calls.
> With KIP-848 the OffsetFetch and OffsetCommit will start using topic IDs in
> the same way, so the new client implementation will provide it when issuing
> those requests. Topic names should continue to be supported as needed by the
> {{{}AdminClient{}}}.
> We should also review/clean-up the support for topic names in requests such
> as the {{METADATA}} request (currently supporting topic names as well as
> topic IDs on the client side).
> Tasks include:
> * Introduce Topic ID in existing OffsetFetch and OffsetCommit API that will
> be upgraded on the server to support topic ID
> * Check topic ID propagation internally in the client based on RPCs
> including it.
> * Review existing support for topic name for potential clean if not needed.
