> -------------------------------------------------------------------------

> Key: FLINK-40386
> URL: https://issues.apache.org/jira/browse/FLINK-40386
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Checkpointing
> Reporter: Rui Fan
> Assignee: Rui Fan
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.4.0
>
>
> StreamTask#recoverChannelsWithCheckpointing produces no log at all today: we
> cannot tell from
> a TaskManager log whether checkpointing during recovery is enabled, nor how
> far the recovery
> got.
> Proposed:
> * INFO when the feature is enabled.
> * INFO/DEBUG on the transitions of the futures chain (fetching -> filtering
> -> draining).
