------------------------------------
Summary: FLIP-503: Blue/Green Deployments for Flink on Kubernetes:
Phase 1 (basic)
Key: FLINK-37515
URL: https://issues.apache.org/jira/browse/FLINK-37515
Project: Flink
Issue Type: New Feature
Components: Kubernetes Operator
Affects Versions: kubernetes-operator-1.11.0
Reporter: Sergio Chong
We identified the need for a solution to have minimal “downtime” when
re-deploying pipelines. This is the case when the startup times are high and
lead to downtime that’s unacceptable for certain workloads.
Flink pipelines require the data stream flow to be halted during deployment
operations. For some cases stopping this data flow could have a negative impact
on downstream consumers.
A Blue/Green deployment architecture can help overcome this issue by starting a
second identical pipeline along side the main one and switching over to it when
the desired criteria is met.
This JIRA represents support for an initially simple Blue/Green deployment as a
new feature for the Flink Kubernetes Operator.
