Hi folks,
FLIP-503 (already merged) introduced the Basic Blue/Green Deployment
functionality to the Flink K8s Operator. It was very straightforward, simply
transitioning to the second deployment once it's considered stable.
FLIP-504 is an Advanced version added on top of 503 and brings about the notion
of "record-level" coordination between the 2 deployments to have no data
duplication and exactly once semantics while preserving a smooth transition.
The main goals are:
• For the community to take a quick look at the current functionality
(previously mentioned at the Flink Forward 2025 Conference)
• To get feedback and improvement suggestions

Thank you!
