U-SQL procedure call order

Let we have script that consists of 3 procedure calls:

mydb.myschema.PopulateDimensions(...)
mydb.myschema.PopulateFactTable(...)
mydb.myschema.UpdateStatistics(...)

Will they be executed in the same order or they will be inlined into the script and the entire mix will be executed in parallel?

Solution

  • They will be inlined and then the compiler, optimizer and scheduler will determine how to best execute the overall script.

    What are you trying to achieve/hope for?
