> Use topic id/name mapping from the Metadata cache in the RemoteLogManager
> -------------------------------------------------------------------------
>
> Key: KAFKA-15038
> URL: https://issues.apache.org/jira/browse/KAFKA-15038
> Project: Kafka
> Issue Type: Task
> Components: core
> Reporter: Alexandre Dupriez
> Assignee: Owen C.H. Leung
> Priority: Minor
> Fix For: 3.7.0
>
>
> Currently, the {{RemoteLogManager}} maintains its own cache of topic name to
> topic id
> [[1]|https://github.com/apache/kafka/blob/trunk/core/src/main/java/kafka/log/remote/RemoteLogManager.java#L138]
> using the information provided during leadership changes, and removing the
> mapping upon receiving the notification of partition stopped.
> It should be possible to re-use the mapping in a broker's metadata cache,
> removing the need for the RLM to build and update a local cache thereby
> duplicating the information in the metadata cache. It also allows to preserve
> a single source of authority regarding the association between topic names
> and ids.
