Guozhang Wang resolved KAFKA-9039. ---------------------------------- Fix Version/s: 2.5.0 Assignee: Lucas Bradstreet Resolution: Fixed > Optimize replica fetching CPU utilization with large number of partitions > ------------------------------------------------------------------------- > > Key: KAFKA-9039 > URL: https://issues.apache.org/jira/browse/KAFKA-9039 > Project: Kafka > Issue Type: Improvement > Components: core > Reporter: Guozhang Wang > Assignee: Lucas Bradstreet > Priority: Major > Fix For: 2.5.0 > > > Our current follower replica fetching logic has huge CPU cost with > num.partitions to fetch from, and it scales non-linearly as well. There are a > bunch of optimizations we can consider to try to reduce its cost and > hopefully make it to be linear against the num.partitions. -- This message was sent by Atlassian Jira (v8.3.4#803005)
