COD now allows you to create edge nodes while creating an operational database. You can define the number of edge nodes to be created, and COD automatically creates and configures the nodes in your COD cluster.
You can also add additional nodes into your COD cluster or delete an existing one using the edge node instance ID.
For more information, see Managing edge nodes.
This is available starting in COD v1.26 and you do not need to upgrade to a higher version of COD to benefit from this feature.
