Enable Pagination for Lineage

Customer Managed Applies to customer-managed instances of Alation

Lineage pagination, available from release 2022.4, enables control over the horizontal extent of lineage diagrams. Extremely large lineage diagrams can be difficult to process and display; pagination helps to keep such diagrams manageable. Pagination requires that Lineage V3 be enabled.

Enable pagination using alation_conf as follows:

1. Use SSH to connect to the Alation server.

2. Enter the Alation shell using the following command:

   sudo /etc/init.d/alation shell
   

3. In alation_conf, set the pagination flag:

   alation_conf lineage-service.features.enable_pagination -s True
   

4. Restart the lineage service:

   alation_supervisor restart lineage
   

5. Exit the Alation shell by typing exit at the prompt:

   exit
   

Once pagination is enabled, you can control the horizontal extent of your lineage diagrams using either the lineage-service.filters.max_depth parameter in alation_conf, or, equivalently, the Initial Horizontal Levels (Distance) control on the Lineage tab of the Customize Catalog menu, as described in Modifying the Number of Nodes Displayed in Lineage Diagrams.
