------------------------------------------
Summary: Add SAVEPOINT_ONLY upgrade mode
Key: FLINK-29258
URL: https://issues.apache.org/jira/browse/FLINK-29258
Project: Flink
Issue Type: New Feature
Components: Deployment / Kubernetes
Reporter: Maximilian Michels
Users may want to explicitly upgrade from a savepoint. the {{SAVEPOINT}}
upgrade mode cannot ensure this. When the savepoint creation fails, which might
be temporary, the operator falls back to using the latest checkpoint.
To prevent this from happening, we could add a SAVEPOINT_ONLY upgrade mode
which does not proceed when the savepoint creation fails.
