To configure metadata extraction (MDE), perform the following steps in your Alteryx data source settings page in Alation’s UI:

  1. Under Extraction Settings, configure the metadata extraction. Turn on Selective Extraction, if required. Selective extraction settings are used to apply a filter to include or exclude Collections (folders).

  2. Click Get List of Folders to first fetch the list of folders from Alteryx.

  3. The status of the Get Folders action is logged in the Job History table at the bottom of the Settings page.

  4. If the folder synchronization is successful, a drop-down list of folders will become enabled. Select one or more folders to extract by clicking the + button.

  5. Choose your desired filter option. Available filter options are:

Filter Option

Description

Extract all Folders except

Extract only these Folders

  1. Click Run Extraction Now to extract metadata from Alteryx. The status of the Extraction action is logged in the Job History table at the bottom of the page.

  2. If you wish to automatically update the metadata in the Catalog, under Automated and Manual Extraction, turn on Enable Automated Extraction and select the day and time when metadata should be extracted. The metadata extraction will be automatically scheduled to run at the selected day and time.
