By upper bound I mean a maximum time that the downstream task can execute during a day. I am using it to fetch data from a device that, for power saving reason, is available only during few hours of a day (ie 1pm -3pm) and this data fetching has to be executed only within that time. Backfilling of the dag in that case is very ineffective - most of the data fetching tasks will fail due to device not being available. I could also imagine that in some cases, if upstream of such time-limited task is taking longer than usual, it might cause getting out of the `safe` time window. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
