Thanks for response @richcollier.
Is it fine that I keep Query delay equal to 1d? I assume the datafeed keeps a track of the point till which it has taken in the data to avoid the duplicate issues. And the only cost for me will be a more expensive query since the time range is bigger.
I am asking this since the data is actually coming from production line. And they run the line when needed. There is no schedule. There maybe days during which they do not make anything. And few days when the run the line 24hrs non stop.
