Administrators can now enable data acceleration for specific workbooks. An accelerated workbook loads faster because Tableau Server precomputes the workbook's data in a background process.
Note: This documentation explains how to configure data acceleration using the Tableau Server REST API. However, the easiest way to configure data acceleration is to use the
accelerate_workbooks.py Python script that you can download from the Tableau Data Acceleration Client(Link opens in a new window) GitHub repository.
For more information about this feature, see Data Acceleration in the Tableau Server documentation.
To configure data acceleration:
- Update a workbook to turn on or off data acceleration by setting the attribute
false. By default, it is disabled. You can also set the
falseto specify whether to start the precomputation for acceleration immediately when the next backgrounder process becomes available.
- Create a schedule of type
- Add a workbook with data acceleration to the schedule.
- Get data acceleration tasks.
- Delete a data acceleration task.
- Get a data acceleration report for a site.
To remove a workbook from a schedule, update the workbook to turn off data acceleration by setting the attribute
accelerationEnabled to false.
Data acceleration is turned on by default for sites. You can update a site to enable or disable data acceleration by setting the attribute
disable. When you disable it, no workbooks are accelerated and all data acceleration tasks are removed from schedules.
When you create a schedule, consider setting the schedule interval to be less than 12 hours. When you attach an acceleration schedule to a workbook, if that acceleration schedule interval exceeds the Tableau Server cache expiration time, the workbook will not be accelerated during the period between the cache expiration time and the next run of the acceleration schedule. The workbook will revert to using the databases. By default, the Tableau Server cache expiration time is 12 hours (720 minutes).
