Before you use Cloud Firestore, you must choose a location for your database. To reduce latency and increase availability, store your data close to the users and services that need it. This location setting is your project's default Google Cloud Platform (GCP) resource location.
Note that your default GCP resource location might have been previously set, either during project creation or when setting up another service that requires a location setting (see below).
Default GCP resource location
Several services available for your app require a location setting, called your project's default Google Cloud Platform (GCP) resource location. This location is where your data is stored for GCP services that require a location setting.
The following products share the same default GCP resource location:
Note that your default GCP resource location does not apply to Firebase Realtime Database.
Google App Engine (GAE) app
If you set up an App Engine app, its location shares your default GCP resource location. Note that if you use Cloud Scheduler (for example, to run scheduled functions), you're required to have an App Engine app in your project.
Types of locations
Note that if you already have an App Engine app with a location of either
europe-west, your Cloud Firestore database will be
Select a multi-region location to maximize the availability and durability of your database. Multi-region locations can withstand the loss of entire regions and maintain availability without losing data.Firebase supports the following multi-region GCP resource locations:
|Multi-Region Name||Multi-Region Description||Constituent Regions|
||United States||us-central1, us-central2 (Oklahoma — private GCP region)|
A regional location is a specific geographic place, such as South Carolina. Data in a regional location is replicated in multiple zones within a region. All regional locations are separated from other regional locations by at least 100 miles.
Select a regional location for lower costs, for lower write latency if your application is sensitive to latency, or for co-location with other GCP resources.Firebase supports the following regional GCP resource locations:
|Region Name||Region Description|
Your Cloud Firestore location type determines the Service Level Agreement (SLA) uptime percentage:
|Covered Service||Monthly Uptime Percentage|
|Cloud Firestore Multi-Region||>= 99.999%|
|Cloud Firestore Regional||>= 99.99%|
Your Cloud Firestore location determines the cost of database operations.
For a comprehensive explanation of pricing per region and per region type, see Understand Cloud Firestore billing.
