What is ConfDB?

ConfDB (configuration database) is a snapd feature that allows snaps to share structured, validated configuration data. It follows a custodian–observer pattern:

• Custodian snaps write configuration to a central store, validated against a JSON schema.
• Observer snaps read that configuration via controlled views.
• Access is governed by interface permissions, providing isolation and type safety.

ConfDB is suited to multi-snap systems where a single source of truth for configuration is needed. For single-snap configuration, standard snap config remains the appropriate choice.
