Stream Analytics

Azure Stream Analytics is a fully managed real-time stream computation service hosted in Microsoft Azure, which provides highly resilient, low latency, and scalable complex event processing of streaming data. Azure Stream Analytics enables developers to easily combine streams of data with historic records or reference data to derive business insights easily and quickly.

  1. 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

  2. Query editor performance problems

    When I open the Query Editor in a Stream Analytics job, my CPU usage spikes and the editor performance can often be measured on the order of _seconds_ per keystroke/mouse click. This reproduces across Edge, IE, and Waterfox.

    Attached is an edge perf trace of one such incident. At ~2.5s, the browser's FPS goes to 0. It remains that way until after almost the 25s mark. A *brief* analysis indicates that it's an issue inside the disposal portion of merge.

  3. 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.

  4. Error message says user defined functions must start with UDF, when actually Machine Learning Functions do now

    So while it could be argued that an Azure ML is or is not a UDF, if a user miss types the name of the AML function, it says user defined functions require udf.

  6. Conversion errors

    When a conversion error happens it would be great to to know wich column was the error source.

    Encountered error trying to write 1 event(s): Conversion from 'System.Int16' to 'System.String' failed.

  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.

  11. Min/Max functions should take DateTime input

    Although this posted as completed, I'm currently receiving error messages telling me that min() and max() cannot take DateTime fields as input, using the latest version of ASA. In the function reference (https://docs.microsoft.com/en-us/stream-analytics-query/min-azure-stream-analytics), only bigint and float are listed as valid inputs.

  15. 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.
