Unexpected network error in Azure Table Storage when autoscale kicks in for Stream Analytics

Scenario

  1. I'm using Azure Stream Analytics (ASA) streaming data from Azure Event Hub to Azure Table Storage.
  2. I've enabled autoscale rule in ASA.
  3. When autoscale kicks in, I notice that there would be a few network errors observed from Azure Table Storage.
    • The timing matched for all observed network errors. So I believe they are not transient.
  4. Checking from Azure Table Storage's StorageTableLogs, all these network errors are failed with:
    • StatusCode: 202
    • StatusTest: InternalError
    • OperationName: EntityGroupTransaction/ InsertOrReplaceEntity

Question

  1. Is this a known behavior?
    • If yes, is there an explanation behind the root cause of these network errors?
    • If no, is there a way for us to retrieve the actual error logs explaining the occurrences of these errors?

Thank you.

    Hello @Ivan Tioh ,
    Thanks for the question and using MS Q&A platform.
    The error which you shared is related to the Table REST API , but i am not sure if you are making any changes on the Table storage side also . I am going to reach out to the internal team and see if we can have some help here .
    Also if you check if in place of writing to Table storage , if you write to blob do you get the same intermittent error ?

    Thanks
    Himanshu
