The enhancements to the Workbook Optimiser allow workbook authors to ignore individual best practices that aren’t relevant to them and implement specific best practices with a single click.
The Tableau Workbook Optimiser is a feature that helps users optimise the performance of their Tableau workbooks. It analyses the structure and queries of a workbook and provides recommendations on how to improve performance, such as reducing data redundancy and optimising data source connections. This can help users to speed up their data visualisation and analysis processes, as well as make their workbooks more efficient and scalable. Additionally, the optimiser can also detect and diagnose any issues that may be causing slow performance, such as poor query design or outdated data source connections. The Workbook Optimiser can be accessed from within the Tableau Desktop application and can be used to optimise both Tableau workbooks and data sources.
