Bandera.Notifications.Redis (bandera v0.1.0)

Copy Markdown

Redis PubSub cache-busting notifier (via Redix). Subscribes to a channel and, on a flag change published by ANOTHER node, busts the local cache entry for that flag. Self-published changes are ignored. Connection options are read at runtime from config :bandera, cache_bust_notifications: [redis: <Redix opts>].

Note: incoming change payloads come from a shared channel. The flag name is resolved with String.to_existing_atom/1, so notifications for flags this node has never referenced are ignored (and the atom table can't be exhausted by foreign publishers).
