Overview
Couchbase Lite supports replication between two local databases at the database, scope, or collection level. This allows a Couchbase Lite replicator to store data on secondary storage. It is useful in scenarios when a user’s device is damaged and its data is moved to a different device.
Example 1. Replication between Local Databases
let targetDatabase = DatabaseEndpoint(database: database2)
var config = ReplicatorConfiguration(target: targetDatabase)
guard let collection1 = try database.collection(name: "collection1", scope: "scope1") else { return }
config.addCollection(collection1)
config.replicatorType = .push
self.replicator = Replicator(config: config)
self.replicator.start()
