Remote Settings¶
Remote Settings is a Mozilla service that makes it easy to manage evergreen settings data in Firefox.
As of Firefox 68, Normandy uses Remote Settings to serve/update its recipes. This allows us to:
Unify the way we obtain fresh data from our services in Firefox
Get rid of the specific data channel of Normandy
Get rid of the specific content signature integration
Get rid of specific client code that fetches recipes from the server
Unify the way we track uptake telemetry, network errors
Speed up uptake
Benefit from Remote Settings push notifications (live update)
Reduce bandwidth using diff-based updates
Server to Server Integration¶
When a recipe is enabled, it is published and becomes visible on the Remote Settings server:
curl ${SERVER}/buckets/main/collections/normandy-recipes/records
When a recipe is disabled, its related record gets deleted.
Manual Synchronization¶
A command allows to synchronize the enabled recipes with the records on the Remote Settings server.
python manage.py sync_remote_settings
Use --dry-run
to only print out the result of the synchronization.
Client side¶
The Normandy client integration was added in Firefox 66 (Bug 1506175), refined through Firefox 67 and 68 (Bug 1538248) and turned on by default in Firefox 68 (bug 1513854).
