Morning all!

 

Ok so the current project that I am working is requiring me to create pretty substantial extract.  The database has contract information that goes back in excess of 10 years.  I am thinking that when all is said and done there is going to be in excess of a million rows but I am not totally sure as an extract of this size is new to me and uncharted territory.

 

I am working in 10.5 and have seen presentations on how to add a blank extract to the server then remove the condition causing it to be blank, letting the server do the heavy lifting.  The problem is that I have tried this and it's failed.  I guess in the update for 10.5 and beyond, Tableau removed this capability.

 

So I configured my extract as normal in the data source pane.  I tried this connection with just a few records, then 10,000 records, then 100,000 records and it worked every time.

 

I am not trying to create the "Full Monty" extract.  When I left work yesterday afternoon the dang thing had been running for 4 hours.  Some where in the middle of the night the process stopped.

 

Just wondering if anyone else has advice on how to do this?

 

Thanks,

    Monica,

     

    I can't say for sure what is the issue is.  That said part of the issue is that the tables are not aggregated at the same level.  While I was writing a custom SQL statement to help with this issue, it just won't work.

     

    That said I had a conversation with my boss and we are going to build one view from one table as a single source.  The other view from the other table as a single source.  Both views will have a common hierarchy that will allow us to filter.  While this does reduce some of Tableau's functionality at this point, hopefully in the future, I can have the DBA go back and create a custom view for me that will accomplish what I was originally trying to do.

     

    Tableau is good and wonderful but poor data structure is hard to work around.

     

    Thanks,
