Jason Gustafson resolved KAFKA-7779. ------------------------------------ Resolution: Fixed > Avoid unnecessary loop iteration in leastLoadedNode > --------------------------------------------------- > > Key: KAFKA-7779 > URL: https://issues.apache.org/jira/browse/KAFKA-7779 > Project: Kafka > Issue Type: Improvement > Components: network > Affects Versions: 2.1.0 > Reporter: huxihx > Assignee: huxihx > Priority: Minor > > In NetworkClient.leastLoadedNode, it invokes `isReady` to check if an > established connection exists for the given node. `isReady` checks whether > metadata needs to be updated also which wants to make metadata request first > priority. However, if the to-be-sent request is metadata request, then we do > not have to check this otherwise the loop in `leastLoadedNode` will do a > complete iteration until the final node is selected. That's not performance > efficient for a large cluster. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
