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.
