Re: High Start-Delay And Aligned Checkpointing Causing Timeout.

Hi, Pritam. I think the definition works for aligned checkpoint and unaligned checkpoint: "The alignment duration, which is defined as the time between receiving first and the last checkpoint barrier. "

Re: High Start-Delay And Aligned Checkpointing Causing Timeout.

I'm not 100% certain what "alignment duration" is measuring exactly in the context of unaligned checkpoints -- however, even with unaligned checkpointing each operator still has to wait until all of the barriers are present in the operator's input queues. It doesn't have to wait for the barriers
