Nick Afshartous commented on KAFKA-6690: ---------------------------------------- There was a comment during the vote that we should look at Samza's {{MessageChoose}} https://samza.apache.org/learn/documentation/0.7.0/api/javadocs/org/apache/samza/system/chooser/MessageChooser.html > Priorities for Source Topics > ---------------------------- > > Key: KAFKA-6690 > URL: https://issues.apache.org/jira/browse/KAFKA-6690 > Project: Kafka > Issue Type: New Feature > Components: consumer > Reporter: Bala Prassanna I > Assignee: Nick Afshartous > Priority: Major > > We often encounter use cases where we need to prioritise source topics. If a > consumer is listening more than one topic, say, HighPriorityTopic and > LowPriorityTopic, it should consume events from LowPriorityTopic only when > all the events from HighPriorityTopic are consumed. This is needed in Kafka > Streams processor topologies as well. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
