--------------------------------
Fix Version/s: 3.1.0
> topicIdsToNames and topicNamesToIds allocate unnecessary maps
> -------------------------------------------------------------
>
> Key: KAFKA-13512
> URL: https://issues.apache.org/jira/browse/KAFKA-13512
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.1.0
> Reporter: Justine Olshan
> Assignee: Justine Olshan
> Priority: Blocker
> Fix For: 3.1.0
>
>
> Currently we write the methods as follows:
> {{def topicNamesToIds(): util.Map[String, Uuid] = {}}
> {{ new util.HashMap(metadataSnapshot.topicIds.asJava)}}
> {{}}}
> We do not need to allocate a new map however, we can simply use
> {{Collections.unmodifiableMap(metadataSnapshot.topicIds.asJava)}}
> We can do something similar for the topicIdsToNames implementation.
