[jira] [Created] (FLINK-25650) Document unaligned checkpoints performance limitations (larger records/flat map/timers/...)

Anton Kalashnikov created FLINK-25650:
-----------------------------------------

             Summary: Document unaligned checkpoints performance limitations (larger records/flat map/timers/...)
                 Key: FLINK-25650
                 URL: https://issues.apache.org/jira/browse/FLINK-25650
             Project: Flink
          Issue Type: Improvement
          Components: Documentation, Runtime / Checkpointing
    Affects Versions: 1.14.0
            Reporter: Anton Kalashnikov


The unaligned checkpoint can be delayed if the current record is consumed too long(because it is too large or it is the flat map etc.). Which can be pretty confused. So it makes sense to document this limitation to give the user understanding of this situation.
