BI Connector's Preload Metadata feature (available from v3.1 to v3.3) helps minimizing the waiting time for loading OBIEE SubjectArea / Reports  in both Tableau and Power BI. 


Now in BI Connector v3.3, this Preload Metadata feature can be enabled seamlessly with less user intervention making it more user friendly.


Here is how it works...


Whenever you add a new report or rename an existing report in your OBIEE server, you have to manually preload the metadata to work with that new report. But with this automatic preload feature, you can a set a time interval during which the subject area tables as well as reports will be preloaded at the background without user intervention. You can configure this time interval based on the frequency of adding / renaming a report in your OBIEE environment.
