Inputs from Blob storage - excessive ListBlobs transactions RRS feed

  • Question

  • I recently noticed an high transaction cost for a storage account associated with stream analytics.

    I have about 16 input streams from General purpose V2 blob storage.
    These Inputs are for exports from application insight continuous export - about 20-30 new blobs are added every minute in total.

    Altogether, these input streams result in between 2 and 3 Million ListBlobs transactions per day
    This turns out to be quite expensive!

    It is querying listBlobs about 100 blobs for every time it reads one!
    Is there any way to configure Azure Stream Analytics to perform less listBlobs operations in this scenario?

  • Hello Johannes Schoeman, and thank you for your inquiry.  Are you open to the idea of doing some pre-aggregation to reduce the quantity of blobs written?

  • Johannes Schoeman, are you still in need of assistance?

  • I'm open to the idea - I just export the blobs using Azure's continuous export, and I didn't see any settings that allowed me to configure the frequency at which it exported.
