Performance Issue with U-SQL code


  • Hi,

    I am executing one stored procedure in U-SQL, initially, it is used to work fine, but from last 3 days, it starts giving issue with performance. It is getting stuck at a certain step, I am not able to identify the exact part of the query in u-SQL which causing a delay in execution.

    I have attached the screenshot of the job graph, It will be great if someone can let me know the way of identifying the issue

    Thankx & regards, Vipin jha MCP

  • This would be a great one to see the actual code you are running

    The only explanation I can think of is a never ending loop.  The output is larger than the product of both inputs.
