Stream Analytics Polling RRS feed

  • Question

  • How frequently does stream analytics job poll the input blobs. Does the performance of polling algorithm get degraded based on the size of my Blob container?

  • Polling interval is between 1 and 5 seconds when you there is a regular supply of new blobs, if there are no new blobs for a long time (> minute), then the interval could be increased to as high as 30 seconds.

    If you don't use date, time based partitions and have a lot of blobs, then the polling will be slow as it has to enumerate all the blobs all the time. If you are using date partition, then there is no significant impact.

    'Size' of the container (which I assume is space used) itself doesn't have any impact.
