ASA Lag is returning a result from outside given duration RRS feed

  • Question

  • I try to use Azure stream analytics to filter results that are too far from the last 2 reads.
    However, if last read is more than 720 minutes back (by reading time) I don't want to discard current read because of this difference. 

    I noticed the following is returning a read from 900 minutes back, which is unexpected as far as I can understand: 

        OVER (PARTITION BY RegisterNumber LIMIT DURATION(minute, 720)) 

    I can ignore this read in my select query but I prefer to understand the reason before give up using the duration feature...

  • Have you tried using the TIMESTAMP BY clause?
