-------------------------------------
Summary: Improve KRaft metadata image change performance at high
topic counts
Key: KAFKA-14735
URL: https://issues.apache.org/jira/browse/KAFKA-14735
Project: Kafka
Issue Type: Improvement
Components: kraft
Reporter: Ron Dagostino
Assignee: Ron Dagostino
Fix For: 3.5.0
Performance of KRaft metadata image changes is currently O(<# of topics in
cluster>). This means the amount of time it takes to create just a *single*
topic scales linearly with the number of topics in the entire cluster. This
impact both controllers and brokers because both use the metadata image to
represent the KRaft metadata log. The performance of these changes should
scale with the number of topics being changed -- so creating a single topic
should perform similarly regardless of the number of topics in the cluster.
