Do I need a separate database for each cinder instance?

I currently have one cinder instance but I need to create another one with a different endpoint. Do I need to point it to a different database?

No, you don't. One cinder database is all you need.

Although note, that cinder-volume processes do NOT connect to the database directly. Instead, they communicate with the cinder process running on the controller node (I believe with the cinder-scheduler), which then communicates with the database on their behalf. You typically need only one cinder-api(controller node), one cinder-scheduler (controller node), and multiple cinder-volume (storage node) processes running.
