Method: projects.export

Exports a copy of all or a subset of entities from Google Cloud Datastore to another storage system, such as Google Cloud Storage. Recent updates to entities may not be reflected in the export. The export occurs in the background and its progress can be monitored and managed via the Operation resource that is created. The output of an export may only be used once the associated operation is done. If an export operation is cancelled before completion it may leave partial data behind in Google Cloud Storage.

HTTP request

POST https://datastore.googleapis.com/v1beta1/projects/{projectId}:export

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
projectId

string

Project ID against which to make the request.

Request body

The request body contains data with the following structure:

JSON representation 
{
  "labels": {
    string: string,
    ...
  },
  "entityFilter": {
    object (EntityFilter)
  },
  "outputUrlPrefix": string
}
Fields
labels

map (key: string, value: string)

Client-assigned labels.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
entityFilter

object (EntityFilter)

Description of what data from the project is included in the export.
outputUrlPrefix

string

Location for the export metadata and data files.

The full resource URL of the external storage location. Currently, only Google Cloud Storage is supported. So outputUrlPrefix should be of the form: gs://BUCKET_NAME[/NAMESPACE_PATH], where BUCKET_NAME is the name of the Cloud Storage bucket and NAMESPACE_PATH is an optional Cloud Storage namespace path (this is not a Cloud Datastore namespace). For more information about Cloud Storage namespace paths, see Object name considerations.

The resulting files will be nested deeper than the specified URL prefix. The final output URL will be provided in the google.datastore.admin.v1beta1.ExportEntitiesResponse.output_url field. That value should be used for subsequent projects.import operations.

By nesting the data files deeper, the same Cloud Storage bucket can be used in multiple projects.export operations without conflict.

Response body

If successful, the response body contains an instance of Operation.
