# Data Acceleration (Retired)

**Important changes for Tableau View Acceleration and Data Acceleration**

Tableau's View Acceleration feature and Data Acceleration APIs are retired. These features were retired in Tableau Cloud in June 2026 and in Tableau Server version 2026.2.

Sever administrators can enable data acceleration for specific workbooks. An accelerated workbook loads faster because Tableau Server precomputes the workbook's data in a background process.

**Notes:**

- This topic 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](https://tableau.github.io/tableau-data-acceleration-client/) GitHub repository.
- Data acceleration is not available for Tableau Cloud.

For more information about this capability, see [Data Acceleration](https://help.tableau.com/v2020.2/server/en-us/data_acceleration.htm) in the Tableau Server Help.

## Configure data acceleration

To configure data acceleration using the REST API, do the following:

- [Update a workbook](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#update_workbook) to turn on or off data acceleration by setting the attribute `accelerationEnabled` to `true` or `false`. By default, it is disabled. You can also set the `accelerateNow` attribute to `true` or `false` to specify whether to start the precomputation for acceleration immediately when the next backgrounder process becomes available.
- [Create a schedule](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#create_schedule) of type `DataAcceleration`
- [Add a workbook with data acceleration to the schedule](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#add_workbook_to_schedule)
- [Get data acceleration tasks](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#get_data_acceleration_tasks)
- [Delete a data acceleration task](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#delete_data_acceleration_task)
- [Get a data acceleration report for a site](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#get_data_acceleration_report)

### Additional notes about data acceleration

- 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](https://help.tableau.com/v0.0/api/rest_api/en-us/REST/rest_api_ref.htm#update_site) to enable or disable data acceleration by setting the attribute `dataAccelerationMode` to `enable_selective` or `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).
