[jira] [Created] (FLINK-29856) Triggering savepoint does not trigger source operator checkpoint
Mason Chen created FLINK-29856:
----------------------------------
Summary: Triggering savepoint does not trigger source operator checkpoint
Key: FLINK-29856
URL: https://issues.apache.org/jira/browse/FLINK-29856
Project: Flink
Issue Type: Improvement
Components: Runtime / Checkpointing
Affects Versions: 1.16.0
Reporter: Mason Chen
When I trigger a savepoint with the Flink K8s operator, I verified for two sources (KafkaSource and MultiClusterKafkaSource) do not invoke snapshotState or notifyCheckpointComplete. This is easily reproducible in a simple pipeline (e.g. KafkaSource -> print).
However, when the checkpoint occurs via the interval, I do see the sources checkpointing properly and expected logs in the output.

This sounds like a pretty serious issue. Has anybody looked into this
already?
