FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

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.

Features

  • 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.

Limitations

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

Locations

Currently, Fauna offers these Region Groups:

  • United States

  • Europe

  • Global

Pricing varies by region. See Pricing for details.

If you want to request a region, product@fauna.com.

Replica distribution

  • United States: three replicas in the United States

  • Europe: three replicas in Europe

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.
