            Azure Streaming Analytics job not connecting to Event Hub input
            Asked 2020-Oct-02 at 11:14

            When I use the Process Data feature within my event hub, I am able to develop a query, see data and get results. However, when I click Deploy Query the query view cannot connect to my event hub and fails with:

            @tyler When you go to Overview of your Event Hub (from the left pane), do you see any incoming events?



            How to convert a 'dictionary-like' structure in Azure Stream Analytics to a multi dimensional array with a javascript UDF?
            Asked 2020-Aug-12 at 08:53

            After using the CollectTop aggregation function of Azure Stream Analytics, I get back a json-like structure that seems to be like a Dictionary of Dictionaries. I need to convert this one to a multi-dimensional array which I want to pass to an AzureML UDF.

            My question is mostly on how I can interpret this structure in a javascript-UDF, as I'm totally new to Javascript.

            This is a sample record (using CollectTop), but the challenge is how my javascript UDF should look like?

            Clarification on how to calculate watermark for Azure Streaming Analytics
            Asked 2020-Jul-14 at 22:39

            I'm working on understanding watermarks in Azure Streaming Analytics. Per MS documentation, there are two ways that watermarks can be calculated.


            The second method states: "When there's no incoming event, the watermark is the current estimated arrival time minus the late arrival tolerance window. The estimated arrival time is the time that has elapsed from the last time an input event was seen plus that input event's arrival time."


            • What is meant by "No incoming events"? Does this mean that the source (ex. Event Hub) is verified to be empty?

            • What is meant by "The last time an input event was seen."? Does this mean when it has exited the processing engine to the source?

            Currently, this is how I interpret the calculation: (7) Watermark = (5) [Estimated Arrival Time] - (6) [Late Arrival Tolerance Window]

            (5) Estimated Arrival Time = (1) [Elapsed Time] + (4) [Last Arrival Time]

            (1) Elapsed Time = Time that elapsed from the (2) [Last time an input event was last seen] and (3) [the current time]



            Answered 2020-Jul-14 at 22:39

            Yes "No incoming events" means that ideally there is nothing to process on the Eventhub .

            For the second part , i think you have already gone through the doc which states

            "When there's no incoming event, the watermark is the current estimated arrival time minus the late arrival tolerance window. The estimated arrival time is the time that has elapsed from the last time an input event was seen plus that input event's arrival time." .

            If we are in the 0:45 mark and if you see that the expected events was at :40 unit ( lets assume that the event is coming in every 5 unit of time ) . so the watermark will be (45-15 (6) in your example)

            I have 2 questions:

            1. Does azure Stream analytics support nested conditions using the CASE statement ?
            2. I see there are 2 formats of CASE expression mentioned here- . I found examples for searched CASE here. Can anyone give example for the Simple CASE expression?

            Dataflow: Look up a previous event in an event stream
            Asked 2019-Mar-21 at 21:18

            Resuming what I'm looking for to do with Apache Beam in Google Dataflow is something like LAG in the Azure Stream Analytics

            Using a window of X minutes where I'm receiving data:



            Answered 2019-Mar-21 at 21:18

            With Beam, as explained in the docs, state is maintained per key and window. Therefore, you can't access values from previous windows.

            To do what you want to do you might need a more complex pipeline design. My idea, developed here as an example, would be to duplicate your messages in a ParDo:

            • Emitting them unmodified to the main output
            • At the same time, send them to a side output with a one-window lag

            To do the second bullet point, we can add the duration of a window (WINDOW_SECONDS) to the element timestamp:



            Limit 1 or Top 1 in Azure Stream Analytics Query
            Asked 2019-Feb-21 at 07:00

            I have written below Stream Analytics Query to get Device Offline status alert. Query gives me an alert if no input received from device in the last 5 minute.

            I need last telematic record (Last known location) of that device, but I'm getting all data sent for that device. I tried LAST and TopOne but all are windowing method. Is there any other solution than a custom function?



            Answered 2019-Feb-21 at 06:59

            I'm able to fix query but not 100 percent. After removing below line from query and it's working, still not clear why it is not working with TimeStamp

            TIMESTAMP BY header.messageTimestamp

            I have 2 queries 1 Device Online Alert and 2nd for Device Offline alert



            How to define overlapping hopping windows in Esper using EPL?
            Asked 2019-Jan-11 at 13:06

            How can I define an overlapping tumbling window as EPL query in Esper? I'm looking for equivalent of hopping windows similar to these:


            For example: 1 second hopping window with 500ms overlap.

            Esper's reference manual describes tumbling windows and overlapping context, but how can I express it as a query?

            Thank you.



            Answered 2019-Jan-11 at 13:06

            The solution is the overlapping context. Things that fire regularly are done with a pattern.
