[jira] [Updated] (KAFKA-8806) Kafka.poll spends significant amount
of time in KafkaConsumer.updateAssignmentMetadataIfNeeded
[ https://issues.apache.org/jira/browse/KAFKA-8806?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xavier Léauté updated KAFKA-8806:
---------------------------------
Description:
Comparing the performance profile of 2.2.0 and 2.3.0, we are seeing significant performance differences in the {{KafkaConumer.updateAssignmentMetadataIfNeeded()}} method.
The call to {{KafkaConsumer.updateAssignmentMetadataIfNeeded()}} now represents roughly 25% of CPU time spent in {{KafkaConsumer.poll()}}, when before it only represented less than 5%.
Most of the extra time appears to be spent in {{KafkaConsumer.validateOffsetsIfNeeded()}}, which did not show up in previous profiles.
