Region Groups

Region Groups is a new Fauna infrastructure that addresses data locality concerns:

  • Region Groups give control over where your data resides: each database, its storage, and its compute services exist in a separate geographic region. The capability makes it possible to comply with data locality legislation, such as the General Data Protection Regulation (GDPR) in Europe, while benefiting from the distributed service features built into Fauna.

  • The nodes in a Region Group are physically located (relatively speaking) close together, which reduces the round-trip time to acknowledge consistent writes (compared to global replication), improving performance for many workloads.


  • Region Group selection exists at the database level.

  • When a database is in a Region Group, it is fully isolated from other Region Groups, and is never replicated to other Region Groups.


  • A database and all of its contents, including child databases, can only exist in a single Region Group.


Currently, Fauna offers three Region Groups:

  • United States

  • Europe

  • Classic (Europe and United States)

Pricing varies by region. See Pricing for details.

More Region Groups may be added in the future. If you want to request a region, contact us.

Replica distribution

  • United States: three replicas in the United States

  • Europe: three replicas in Europe

  • Classic: two replicas in the United States, one replica in Europe

Region Group endpoints

FQL queries

Fauna uses an intelligent routing layer that connects your client applications to the Region Group for your database based on the secret. No change to your client applications is required to use Region Groups. See Connections for guidance on client application connections.
