Microsoft EmployeeError in importing larget dataset for Azure data Explorer with truncation set to false
I am trying to import data a table having '1233587' rows from Azure data explorer, and facing below error : Even though I have set disable truncation to TRUE and '1233587' rows doesnt exceed the limit '2147483647' in below error message.

Hi rumittal ,
I think it is caused by the import mode. When our data set is very small, we could use import mode. For your requirement, there are '1233587' rows in your data model. You could try Direct Query mode. And change the option of "Disable result-set trunction" to false. Then it will generate a set truncation.
Here are the related documents that you could reference.

Hi rumittal ,
Have you solved the issue? If yes, you could share the solution. More people who experience it will benefit here. If no, do you try to change connection mode that I suggested? Is there any error message?
