How can you create a performance recording without using cache?

Creating a performance recording without using cache can be effectively achieved by appending the parameter "refresh=yes" at the end of the URL. This command signals Tableau Server or Tableau Online to bypass any cached versions of the data and fetch fresh data directly from the underlying data source every time the workbook is accessed. This approach ensures that the recorded performance metrics reflect the true performance of the queries being executed in real-time, rather than potentially misleading data that could stem from cached results.

Utilizing cache is a common practice for optimization, as it enhances loading times by serving pre-stored data. However, in performance testing contexts, where the goal is to benchmark real query efficiency, it is crucial to capture performance metrics on un-cached data to understand the capabilities and limitations of the querying process. Thus, the method of adjusting the URL to include "refresh=yes" is an essential technique for obtaining accurate performance recordings.
