When you provision a Realtime Database instance, you must choose a location for the
instance. To reduce latency and increase availability, store your data close to
the users and services that need it.
If your project is on the pay-as-you-go Blaze pricing plan, then you can optionally
create multiple databases in your project, each
with its own location setting.
Be aware that once you provision a database instance, you cannot change its
location setting.
In the following table, find the supported locations for Realtime Database instances
along with their associated database URL formats.
