Gets multiple documents. Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

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-beta1 --scope <scope> projects databases-documents-batch-get ...

Required Scalar Argument

• <database> (string)
  • Required. The database name. In the format: 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:

BatchGetDocumentsRequest:
  documents: [string]
  mask:
    field-paths: [string]
  new-transaction:
    read-only:
      read-time: string
    read-write:
      retry-transaction: string
  read-time: string
  transaction: 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 . documents=et
  • The names of the documents to retrieve. In the format: projects/{project_id}/databases/{database_id}/documents/{document_path}. The request will fail if any of the document is not a child resource of the given database. Duplicate names will be elided.
  • Each invocation of this argument appends the given value to the array.

• mask field-paths=magna

  • The list of field paths in the mask. See Document.fields for a field path syntax reference.
  • Each invocation of this argument appends the given value to the array.

• ..new-transaction.read-only read-time=no

  • Reads documents at the given time. This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

• ..read-write retry-transaction=ipsum

  • An optional transaction to retry.

• ... read-time=voluptua.

  • Reads documents as they were at the given time. This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.
• transaction=at
  • Reads documents in a transaction.

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").
