----------------------------------
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.
