Small operations
Small operations include:
- Calls to allocate IDs.
- Keys-only queries. A keys-only query is counted as a single entity read for the query itself. The individual results are counted as small operations.
- Projection queries that do not use the
distinct onclause. This type of query is counted as a single entity read for the query itself. The individual results are counted as small operations.
Small operations are free, but you must enable billing to exceed the free quota per day.
Network bandwidth
You are charged for the network bandwidth used by your Firestore in Datastore mode requests, as shown in the following sections. The network bandwidth cost of a request depends on the request's response size, the location of your Datastore mode database, and the destination of the response.
General network pricing
For requests that originate within Google Cloud Platform (for example, from an application running on Google Compute Engine), you are charged as follows:
| Traffic type | Price |
|---|---|
| Ingress | Free |
| Egress within a region | Free |
| Egress between regions in the same multi-region | Free |
| Egress between regions within the US (per GiB) | $0.01 (first 10 GiB per month are free) |
| Egress between regions, not including traffic between US regions | Google Cloud Platform internet egress rates |
If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
Internet egress rates
You will be charged for internet egress for the following:
- Google Cloud requests between regions, not including traffic between US regions
- Requests from outside of Google Cloud
Export and import operations
Export and import operations are charged for entity reads and writes at the rates shown in the table above. If you cancel an export or import, you will be charged for operations performed up until the time that the cancel request has propagated through Firestore in Datastore mode.
Locating quota usage information for your app
To see your application's Datastore mode usage, including quota consumption, visit the App Engine Quota Details page. You'll need to do this even if your application does not run in App Engine.
The Datastore mode resources used by your application are listed in the Storage page that is displayed. You can optionally click Show resources not in use to take a look at the complete list of quota information that is available.
Storage size consideration
It's important to note that data stored in Firestore in Datastore mode may incur significant storage overhead. This overhead depends on the number and types of associated properties, and includes space used by built-in indexes and composite indexes. Each entity stored in your database requires the following metadata:
- The entity key, including the kind, the ID or key name, and the keys of the entity's ancestors.
- The name and value of each property. Since Firestore in Datastore mode is schemaless, the name of each property must be stored with the property value for any given entity.
- Any built-in and composite index rows that refer to this entity. Each row contains the entity kind, any number of property values depending on the index definition, and the entity key.
