> Key: FLINK-24530
> URL: https://issues.apache.org/jira/browse/FLINK-24530
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream, Connectors / Common
> Affects Versions: 1.14.0, 1.13.2, 1.15.0
> Reporter: Fabian Paul
> Assignee: Arvid Heise
> Priority: Major
> Labels: pull-request-available, stale-assigned
>
> If a pipeline has a unified Sink that implements a {{Committer}} and
> {{GlobalCommitter}} committables are forwarded from the {{Committer}} on
> either receiving {{notifyCheckpointCompleted}} or {{endInput}}.
> Since both methods are triggered by RPC calls we currently do not guarantee
> an order when either method is called on the {{Committer}} or
> {{GlobalCommitter}}. This can lead to that the {{GlobalCommitter}} receives
> the RPC call at first and tries to commit although the {{Committer}} has
> nothing forwarded yet. For the normal streaming execution, it means that the
> visibility of the final commit could be delayed by one checkpoint.
> Unfortunately, if the pipeline is stopped with a savepoint and drained the
> {{endInput}} might be called at the {{GlobalCommitter}} before the
> {{Committer}} leading to potential data loss.
