# Tableau Server Data Source Properties Service

Introduced in version 2020.1.0, the Tableau Server Data Source Properties service provides metadata for published data source from the Application Server (VizPortal) to client services like Ask Data.

> [!WARNING]
> 
> **Note**: Tableau's Ask Data feature was retired in Tableau Cloud in February 2024 and in Tableau Server version 2024.2.

One instance of the Data Source Properties service is configured on the initial node of Tableau Server. You can add additional instances on the initial node or on other nodes in a multi-node installation. You are required to configure at least one instance of the Data Source Properties service on any node that has an instance of Application Server.

## Log files for the Data Source Properties service

The Data Source Properties service creates two sets of log files:

- `control-tdsservice*.log`. These logs will contain information about the service starting and being enabled.
- `tdsservice_*.log`. Any errors or problems are logged here.

For more information, see [Log File Snapshots (Archive Logs)](https://help.tableau.com/current/server-linux/en-us/logs_archive.htm).

## Data Source Properties service in a multi-node cluster

How you configure the Data Source Properties service in a multi-node cluster depends on how you configure your nodes. In any installation of Tableau Server you must have at least one instance of the service. In addition, you are required to configure at least one instance of Data Source Properties on any node that is configured with the Application Server (VizPortal).
