Justine Olshan created KAFKA-13512: -------------------------------------- Summary: 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
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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
