Does Tableau automatically generate the DML or is it user generated?
Is the table used for multiple sessions or only for a single session?
Does other session create the same/similar tables for use?

As Kunal mentioned temporary tables may the way to go.

    It looks like your system is trying to create the attributes table concurrently. Based
on the name of the table, my hunch is that your workflow(s) is/are trying to generate tables
with the same name (attributes) for use in reporting. 
    
    The suggested way to work around this is to use a naming convention that hints to the
report(s) that will leverage the tables.
    
    So, instead of 2 or more reports trying to create the same 'attributes' table, how about
you try something like .. 'attr_report1' .. 'attr_report2' , etc. ?
    
    Also, if these tables are transient in nature, you can consider using the 'create temp
table as ...'  SQL. This will create temporary tables with the lifespan of the connection
you're working on. The moment you close that connection, Drill will clean up. So, if you have
multiple connections trying to create a temporary 'attributes' table, they will all be isolated.

    
    Hope that helps. Let us know how else you are using Drill.
    
    Thanks

    Subject: Drill Push to Tableau, Error -
    
    Hello,
    
    We are currently running a project which is utilizing the Drill push to Tableau function
to be able to work with our data sets, we are already working with Tableau regarding our needs
and determined that this is our best course of action considering how large data sets are
- over 2 million rows per day.
    
    At the moment we have several visualizations we have published, but we are running in
an issue each morning where some of them are not updating according to our schedules, and
when we review the logs we find some the same type of "fatal" errors that do not always allow
the visualizations to update.
    
    I have reached out to our account rep through Tableau for possible guidance, however,
you might be a more appropriate resource; any help you could provide would be appreciated,
I have not been able to find much via the internets.
    
    Below is a sample of the error codes we are seeing, please let me know you are able to
assist or if you need any additional information. Thank you!
