ReplicaSafe

@ReplicaSafe()
export default class Lesson extends ApplicationModel {

If you have Dream models that are mostly read, seldom written, it can be advantageous to set up a read-only database replica. A model with the @ReplicaSafe decorator will send read queries (find/findOrFail, findBy/FindOrFailBy, first/firstOrFail, all, etc.) to the read-only replica. (Note: within a transaction, all queries are directed to the primary database.)

See database config to configure Dream with your read replica.
