xCluster deployment

Unidirectional (master-follower) and bidirectional (multi-master) replication

This page documents the preview version (v2.23). Preview includes features under active development and is for development and testing only. For production, use the stable version (v2024.1). To learn more, see Versioning.

By default, YugabyteDB provides synchronous replication and strong consistency across geo-distributed data centers. However, many use cases do not require synchronous replication or justify the additional complexity and operating costs associated with managing three or more data centers. A cross-cluster (xCluster) deployment provides asynchronous replication across two data centers or cloud regions. Using an xCluster deployment, you can use unidirectional (master-follower) or bidirectional (multi-master) asynchronous replication between two universes (aka data centers).

For information on xCluster deployment architecture, replication scenarios, and limitations, refer to xCluster replication.
