15.11. Template URLs in cell mappings

You can create templates for the --database_connection and --transport-url in cell mappings with variables that are dynamically updated each time you query the global database. The values are taken from the configuration files of the Compute nodes.

The format of a template URL is as follows:

{scheme}://{username}:{password}@{hostname}/{path}

The following table shows the variables that you can use in cell mapping URLs:
