On a SQL Server 2014, I have an SSAS tabular model which is querying a relational clustered columnstore table (with 800 mio. records), when the model is being processed. The query is just a simple SELECT statement with no joins, filters, etc. I am processing the model through an XMLA command, which is being fired by a SQL Server Agent job. The processing takes a couple of hours.

To get an idea of the progress of the processing, I would like to know the number of records returned so far by the SELECT statement. Is there any way to do this, when I know the SPID of the SELECT statement?

sys.dm_exec_requests does not seem to contain any record count information.

Also, I have tried to look in the DMV's of Analysis Services, to see if any of these objects could give me the information I need, but no luck.

The reason I think it must be possible to obtain this information somehow, is that when I process the tabular model through the graphical IDE of SSMS, it actually shows the row count while processing.

Update: It turns out the sys.dm_exec_requests DMV actually has a row_count column. Unfortunately, the contents of this column does not seem to reflect reality. For the first hour or so of processing, it had the value of "3", but I know from experience that several million records would have been returned within the first hour.

  • Have you tried sys.dm_exec_query_profiles? msdn.microsoft.com/en-gb/library/dn223301.aspx Commented Apr 1, 2016 at 8:22
  • Just did. This dmv does not return any records. Looks like I had to enable SET STATISTICS PROFILE ON before I started the processing, for this to work.

If you connect SQL Server Profiler to SSAS and watch the Progress Report Current events with an EventSubclass=ReadData the IntegerData column will show the cumulative rows read so far for that SSAS partition.

Integerdata: Contains the integer data associated with the reported event, such as the current count of the number of rows processed for a processing event.
