Zhihao Wang created KAFKA-13291: ----------------------------------- Summary: Using Stateful Blue/Green Deployment to handle Application Evolvement Key: KAFKA-13291 URL: https://issues.apache.org/jira/browse/KAFKA-13291 Project: Kafka Issue Type: Improvement Reporter: Zhihao Wang
Application Evolvement is an open problem in streaming processing. We present a *stateful blue/green deployment* to address it. To our knowledge, this is the first general way to handle streaming application evolvement. Here is the design doc: [https://docs.google.com/document/d/1QCnhtrgcMRUWCw_SO7vmfj6dyzbdjIAxWkJzKK4d508|https://docs.google.com/document/d/1QCnhtrgcMRUWCw_SO7vmfj6dyzbdjIAxWkJzKK4d508/edit?usp=sharing] The design requires a daemon job to keep syncing between two Kafka topics with the semantics mentioned in doc. Please review the document and to see if Kafka community can support such a daemon job. -- This message was sent by Atlassian Jira (v8.3.4#803005)
