Matthias J. Sax updated KAFKA-6646: ----------------------------------- Labels: needs-kip (was: ) > Add a GlobalKStream object type for stream event broadcast > ---------------------------------------------------------- > > Key: KAFKA-6646 > URL: https://issues.apache.org/jira/browse/KAFKA-6646 > Project: Kafka > Issue Type: New Feature > Components: streams > Affects Versions: 1.1.0 > Reporter: Antony Stubbs > Priority: Major > Labels: needs-kip > > There are some use cases where having a global KStream object is useful. For > example, where a single event is sent, with very low frequency, to a cluster > of Kafka stream nodes to trigger all nodes to do some processing of state > stored on their instance. > Workaround currently is to either create a second kstream app instance, being > careful to configure it with a different state dir, and give it a unique app > name per instance, then create a kstream in each one. Or - you can use the > normal consumer client inside your kstream app with unique consumer groups. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
