To do this > the CheckpointCommitter has to be able to dynamically > take the subtaskIdx as a parameter when asking > if a checkpoint was committed and also change the > state kept by the GenericWriteAheadSink to also > include that subtask index of the subtask that wrote > the pending checkpoint. > This change is also necessary for making the operator rescalable. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
