title: Tableau performance issue with Tabular Object Model
body: <p>We have developed a model in Tabular Object Model(TOM), &lt;= 3.5 GB in size., and built few Tableau Dashboard(s) on top of this model.</p>
  
  <p>Each dashboard is built by dragging multiple sheets into one dashboard. All the sheets (dragged in one dashboard) fetch data from one fact table (of course it has relationships with Date and other related dimensions) in TOM.</p>
  
  <p>Now, when we interact with Tableau dashboard, we see a performance degradation. When we checked the SQL profiler, Tableau is generating a huge query for almost every interaction that we have with the dashboard.</p>
  
  <p>We checked the huge query and observed that it includes the DAX/query for almost all the measures in fact tables, irrespective of whether the fact table is used in the said dashboard or not.</p>
  
  <p>We have verified the filter settings in the dashboard, the settings are applicable only for the sheets dragged in our dashboard, so there is no question of visualizations getting changed in other dashboards.</p>
  
  <p>Ironically, we still see that Tableau is creating a huge query and incorporating all the DAX/queries and this results into performance impact.</p>
  
  <p>Is there any way we can restrict this behavior?</p>
