Dawid Wysakowicz reassigned FLINK-25256: ---------------------------------------- Assignee: (was: Dawid Wysakowicz) > Savepoints do not work with ExternallyInducedSources > ---------------------------------------------------- > > Key: FLINK-25256 > URL: https://issues.apache.org/jira/browse/FLINK-25256 > Project: Flink > Issue Type: Bug > Components: Runtime / Checkpointing > Affects Versions: 1.14.0, 1.13.3 > Reporter: Dawid Wysakowicz > Priority: Major > > It is not possible to take a proper savepoint with > {{ExternallyInducedSource}} or {{ExternallyInducedSourceReader}} (both legacy > and FLIP-27 versions). The problem is that we're hardcoding > {{CheckpointOptions}} in the {{triggerHook}}. > The outcome of current state is that operators would try to take checkpoints > in the checkpoint location whereas the {{CheckpointCoordinator}} will write > metadata for those states in the savepoint location. > Moreover the situation gets even weirder (I have not checked it entirely), if > we have a mixture of {{ExternallyInducedSource(s)}} and regular sources. In > such a case the location and format at which the state of a particular task > is persisted depends on the order of barriers arrival. If a barrier from a > regular source arrives last the task takes a savepoint, on the other hand if > last barrier is from an externally induced source it will take a checkpoint. -- This message was sent by Atlassian Jira (v8.20.1#820001)
