[jira] [Created] (KAFKA-13291) Using Stateful Blue/Green Deployment

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.
