XDF Output Tool
The XDF Output tool writes a data stream to an XDF (.xdf) file, which is the format used by Microsoft R ScaleR functions for scaling predictive analytics.
This tool uses the R tool. Go to Options > Download Predictive Tools and sign in to the Alteryx Downloads and Licenses portal to install R and the packages used by the R Tool. See Download and Use Predictive Tools.
- In Select the fields to include in the XDF File, select the data you want to have available for predictive analytics using tools enabled with ScaleR.
- In The number of records per write, select the number of records to be written to the .xdf file in each sequential set of batches.
- Select Save the XDF file to a permanent location to save the .xdf file instead of storing it as a temporary file.
- The name of the new XDF file: Click the Save icon to navigate to a location and name the .xdf file.
The output of the tool includes a data stream that contains two records, including the data schema and a key that downstream tools use to locate the .xdf file and understand the field level structure of that field.
