Issue

When upgrading to Tableau Server 10.5.0 - 10.5.7 or 2018.1.0, slower performance from previous versions could be detected after upgrading. This happens if the workbook is using row-level security or user-filters.

Environment

  • Tableau Server 10.5.0 - 10.5.7

Resolution

This is related to known issue ID 750317 that was resolved in the 2018.1.1 release of Tableau Server.  For resolution, upgrade to 2018.1.1 or later. 
 

Cause

Hyper calculated "IN" clauses differently than the older engine, which resulted in slower performance on these queries.
