  1. 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

  2. Bug: Reading the reference data test input from CSV file does not work. Switching back to JSON works well.

    Tried to test my query with IoT Hub as a Data Stream Source and SQL Database as a reference input. I have added the JSON message as a Data Stream test input and CSV file as the reference file input. Testing the query does not provide any results, neither errors. Converting the CSV file to JSON and re-running the test, works well.

  3. How to check for data loss in Stream Analytics

    ◾️Configuration
    In the steps Azure IoT Hub-Azure Stream Analytics-Azure Data Lake Storage, the data of Device-to-Cloud Messaging of Azure IoT Hub is accumulated in Table Storage and Data Lake Storage.

    ◾️Problem
    When Runtime Errors occur in Stream Analytics in this configuration, I can see the details of the error in the activity log, but I don't know how to determine if this error is causing data loss.

    ◾️Request
    Instead of comparing the number of input and output data of Stream Analytics, I would like to compare the contents of data output from the IoT Hub with the contents of data…

  4. Support SQL DB stored procedures as ASA Output

    Allow native support to Stored Procedures to be called from Stream Analytics. This way, we don't need to build custom solutions to trigger Stored Procedures when ASA generates O/P.

  5. Alert per partition

    I would like to create an alert per partition to get informed when a specific partition has high utilization or doesn't create any output event. In the production system, we had it last week that three partitions didn't created any output events over 5 1/2 days. With a retention period of 7 days in the eventhub, it was hard to reprocess the data within the timeframe.

  8. Job Diagram

    This Job Diagram holds real promise as visual intuitive view of job execution and metrics especially during development. In it current form it's anything but that. When I select an output it seems to default to out of order events only.

  9. improve sample data user experience

    Currently i get no feedback when sample data is uploaded or not.
    Also every time i update query, i am asked to upload sample data again which is time consuming activity.

    Even when i sample data from live stream, it still asks me to upload data from file.

    "Ocassionally", when same data is pulled from live stream. I get a notification to download this data. Once this notification disappears, there is no way to get that file again

  10. Add support for compressed output

    I have historic data imported through spark in avro format to our Gen 1 Data Lake. I am now using ASA to stream the live data.
    Spark defaults to uses snappy to compress avro files where as ASA doesn't compress. This has resulted in a 10 fold increase in storage size and a slow down in access speed. Can you add support for compression of the outputs in ASA?

  12. Duplicate Outputs

    If i want to insert data to sql table from different query then query editor won't allow to use same output to use in different queries even though destination must be same. It will be duplication of output.

  14. Support IoTHub.* in Azure Stream Analytics Tools for Visual Studio

    When authoring a query in the portal, I use the IoTHub object to get at items like IoTHub.EnqueuedTime (discussed here: https://docs.microsoft.com/en-us/azure/stream-analytics/stream-analytics-define-inputs#stream-data-from-iot-hub) These do not work in the ASA tools for Visual Studio.

    When you use stream data from an IoT Hub, you have access to the following metadata fields in your Stream Analytics query:
    Property
    Description
    EventProcessedUtcTime
    The date and time that the event was processed.
    EventEnqueuedUtcTime
    The date and time that the event was received by the IoT Hub.
    PartitionId
    The zero-based partition ID for the input adapter.
    IoTHub.MessageId
    An ID that's used to correlate two-way communication in…

  15. Azure Stream Analytics cannot see event hubs in same subscription

    If you want to add Event Hub as stream input of your Azure Stream Analytics, you can't add it through portal even the event hub in the same subscription, the same resource group.

  19. Job Diagram - Retain selected chart metrics

    When viewing the historic replay information in the Stream Analytics Job Diagram. It is frustrating that the chart metrics that are displayed are reset every time you change the replay date or time and click submit.

    Expected outcome of this request is:
    When I change the chart to only display the "Output Events" metric and I then change the replay period then then the "Output Events" are still the only metric displayed and the only change is the updated time axis.
