Hi ShuQi, Auto-creation of streams depends on your Kafka server configuration. In case of coordinator stream and checkpoint stream, samza explicitly creates a stream with 1 partition before publishing to it. This doesn't apply for metrics. So, if auto-creation is turned off in kafka server, then you have to manually create it, as you did.
Glad you figured it out. Cheers!
