-----------------------------------------
Summary: Use topic id/name mapping from the Metadata cache in RLM
Key: KAFKA-15038
URL: https://issues.apache.org/jira/browse/KAFKA-15038
Project: Kafka
Issue Type: Sub-task
Reporter: Alexandre Dupriez
Assignee: Alexandre Dupriez
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.
