----------------------------------
Summary: Some checkpoint metrics rely on latest stat snapshot
Key: FLINK-6171
URL: https://issues.apache.org/jira/browse/FLINK-6171
Project: Flink
Issue Type: Bug
Components: Metrics, State Backends, Checkpointing, Webfrontend
Reporter: Ufuk Celebi
Some checkpoint metrics use the latest stats snapshot to get the returned
metric value. These snapshots are only updated when the {{WebRuntimeMonitor}}
actually requests some stats (web UI or REST API).
In practice, this means that these metrics are only updated when users are
browsing the web UI.
Instead of relying on the latest snapshot, the checkpoint metrics should be
directly updated via the completion callbacks.
