The confdb interface enables snaps to access to specific confdb views.
There are two fields that together identify the view being accessed: account and view. There is also an optional role field which may only take the value of “custodian”, if the snap is a custodian for the confdb-schema being accessed.
See the Confdb configuration mechanism for implementation details, and Configure snaps with confdb to use confdb with your own snaps.

read-sensor-params:
interface: confdb
account: acme
view: sensors/read-sensor1-parameters
See Interface management and Supported interfaces for further details on how interfaces are used.
Confdb is currently considered an Experimental feature and implementation details may change as development progresses.
Developer details
Auto-connect: no, but plugs are auto-connected if the confdb’s account is the same as the snap’s publisher.
