Overview
Couchbase Lite supports replication between two local databases. This allows a Couchbase Lite replicator to store data on secondary storage. It is especially useful in scenarios where a user’s device may be damaged and its data moved to a different device.
Example 1. Replication between Local Databases
-
Kotlin
-
Java
val repl = Replicator(
ReplicatorConfigurationFactory.create(
database = database1,
target = DatabaseEndpoint(database2),
type = ReplicatorType.PULL
)
)
// Create replicator (be sure to hold a reference somewhere that will prevent the Replicator from being GCed)
repl.start()
replicator = replDatabaseEndpoint targetDatabase = new DatabaseEndpoint(database2);
ReplicatorConfiguration replicatorConfig = new ReplicatorConfiguration(database1, targetDatabase);
replicatorConfig.setReplicatorType(ReplicatorConfiguration.ReplicatorType.PUSH);
// Create replicator (be sure to hold a reference somewhere that will prevent the Replicator from being GCed)
replicator = new Replicator(replicatorConfig);
replicator.start();
