Region groups
Region groups give you control over where your data resides. Each database, including storage, and compute services exist in a separate geographic region. This makes it possible to comply with data locality legislation, such as the General Data Protection Regulation (GDPR) while benefiting from the built-in Fauna distributed service features.
Region group nodes are physically located relatively 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 in other region groups.
A database and all its contents, including child databases, can exist only in a single region group.
