Choosing region

RayDB allows you to deploy your PostgreSQL clusters in different geographic regions to optimize performance, reduce latency, and comply with data residency requirements.

Choosing a Region

• When creating a new cluster, you can select the deployment region that best serves your users.
• Available regions are displayed in the Cluster Creation page in the RayDB Dashboard.
• Choosing a region closer to your application servers or users can improve query performance.

Changing a Cluster's Region

• Once a cluster is deployed, its region cannot be changed directly.
• To move a cluster to a new region:
  1. Create a new cluster in the desired region.
  2. Use logical backup and restore (pg_dump and pg_restore) to migrate data.
  3. Update application connection settings to point to the new cluster.

Multi-Region Deployments

• Business plans support read replicas in different regions for improved redundancy and low-latency reads.
• Multi-region configurations can be set up in the Replication section of the dashboard.

Best Practices

• Select the closest region to your primary user base for best performance.
• Consider multi-region read replicas for high availability and failover options.
• Ensure compliance with local data residency regulations when selecting a region.
