Exports a copy of all or a subset of documents from Google Cloud Firestore to another storage system, such as Google Cloud Storage. Recent updates to documents 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. For more details on export behavior and output format, refer to: https://cloud.google.com/firestore/docs/manage-data/export-import

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/datastore

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: firestore1 --scope <scope> projects databases-export-documents ...

Required Scalar Argument

  • <name> (string)
    • Required. Database to export. Should be of the form: projects/{project_id}/databases/{database_id}.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

GoogleFirestoreAdminV1ExportDocumentsRequest:
  collection-ids: [string]
  namespace-ids: [string]
  output-uri-prefix: string
  snapshot-time: string

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r . collection-ids=nonumy
    • Which collection ids to export. Unspecified means all collections.
    • Each invocation of this argument appends the given value to the array.
  • namespace-ids=et
    • An empty list represents all namespaces. This is the preferred usage for databases that don't use namespaces. An empty string element represents the default namespace. This should be used if the database has data in non-default namespaces, but doesn't want to include them. Each namespace in this list must be unique.
    • Each invocation of this argument appends the given value to the array.
  • output-uri-prefix=gubergren
    • The output URI. Currently only supports Google Cloud Storage URIs of the form: gs://BUCKET_NAME[/NAMESPACE_PATH], where BUCKET_NAME is the name of the Google Cloud Storage bucket and NAMESPACE_PATH is an optional Google Cloud Storage namespace path. When choosing a name, be sure to consider Google Cloud Storage naming guidelines: https://cloud.google.com/storage/docs/naming. If the URI is a bucket (without a namespace path), a prefix will be generated based on the start time.
  • snapshot-time=justo
    • The timestamp that corresponds to the version of the database to be exported. The timestamp must be in the past, rounded to the minute and not older than earliestVersionTime. If specified, then the exported documents will represent a consistent view of the database at the provided time. Otherwise, there are no guarantees about the consistency of the exported documents.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p $-xgafv=string

    • V1 error format.

  • -p access-token=string

    • OAuth access token.

  • -p alt=string

    • Data format for response.

  • -p callback=string

    • JSONP

  • -p fields=string

    • Selector specifying which fields to include in a partial response.

  • -p key=string

    • API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.

  • -p oauth-token=string

    • OAuth 2.0 token for the current user.

  • -p pretty-print=boolean

    • Returns response with indentations and line breaks.

  • -p quota-user=string

    • Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.

  • -p upload-type=string

    • Legacy upload protocol for media (e.g. "media", "multipart").

  • -p upload-protocol=string

    • Upload protocol for media (e.g. "raw", "multipart").
