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
CBLDatabaseEndpoint *targetDatabase = [[CBLDatabaseEndpoint alloc] initWithDatabase:self.otherDB];
CBLCollectionConfiguration *collectionConfig = [[CBLCollectionConfiguration alloc] initWithCollection:self.collection];
CBLReplicatorConfiguration *replConfig = [[CBLReplicatorConfiguration alloc] initWithCollections:@[collectionConfig] target:targetDatabase];
replConfig.replicatorType = kCBLReplicatorTypePush;
self.replicator = [[CBLReplicator alloc] initWithConfig:replConfig];
[self.replicator start];
