When using a Redshift data source from Tableau Desktop, you are unable to set the number of slots that a custom SQL query will use.

  • Redshift


Tableau Desktop is unable to change the configuration of data sources. By design, Tableau Desktop is a read-only program to ensure that users will not accidentally overwrite important data or break the database.


Redshift does not have a way to set the number of slots either in the connection to a data source or in the query itself.
