  3. Enable output message size of 1MB from Azure Stream Analytics to Premium Service Bus

    Premium Service Bus allows messages of up to 1MB but Stream Analytics only allows to send messages of 256KB to Premium Service Bus

  4. Include complete analytics offerings in Free Subscription for Evaluation

    I had signed in for the Microsoft Azure ML Free trial. However, as I researched further, I found Azure Streaming Analytics very interesting and wanted to setup an end to end ML + Streaming Architecture as suggested in one of the Tutorial Architecture documents.

    However, since Streaming Analytics cannot be included in the ML Free subscription, I am not able to build an end to end architecture.

    Would be great if a complete analytics set of services is made available under the Free subscription for research.

    Thanks.

  7. Blob

    Infer timestamps from blob filenames instead of metadata. I just bulk uploaded my back data in order to test (one blob per day of data, with YYYY-MM-DD names). But ASA appears to be using the blob LastModified timestamp property to determine whether the data should be included or not. The problem is that the LastModified dates ended up out of order, and worse, are from today, not from the previous months from when the data was collected originally.

  8. BUG: Reference Data from SQL database not working well

    I have a query where I use JOIN clause to join the reference data. Running the test with test files works. Reference Input SQL Query works and retrieves the results so that query is not the problem.
    When testing the ASA Job with real data, it does not retrieve the results, even I send the same message as in the test. Switching reference input to JSON file from BLOB storage makes it working

  10. I would prefer for a given windowing mechanism, to operate across rows that are extracted from the inputs

    Today a UDF function operates on row by row it would be good to have a udf that can created and operate across rows. This enbles in writing more powerful function.

  13. allow APPLY statement for reference data that arrives as nested array

    a current workaround is to send a field that contains the index of each item to be able to do a JOIN.
    if APPLY would be possible, it would be much easier to read value and index directly from the array.
