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

Args:
  database: string, Required. The database name. In the format: `projects/{project_id}/databases/{database_id}`. (required)
  body: object, The request body.
    The object takes the form of:

{ # The request for Firestore.BatchGetDocuments.
    &quot;documents&quot;: [ # 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.
      &quot;A String&quot;,
    ],
    &quot;mask&quot;: { # A set of field paths on a document. Used to restrict a get or update operation on a document to a subset of its fields. This is different from standard field masks, as this is always scoped to a Document, and takes in account the dynamic nature of Value. # The fields to return. If not set, returns all fields. If a document has a field that is not present in this mask, that field will not be returned in the response.
      &quot;fieldPaths&quot;: [ # The list of field paths in the mask. See Document.fields for a field path syntax reference.
        &quot;A String&quot;,
      ],
    },
    &quot;transaction&quot;: &quot;A String&quot;, # Reads documents in a transaction.
    &quot;newTransaction&quot;: { # Options for creating a new transaction. # Starts a new transaction and reads the documents. Defaults to a read-only transaction. The new transaction ID will be returned as the first response in the stream.
      &quot;readOnly&quot;: { # Options for a transaction that can only be used to read documents. # The transaction can only be used for read operations.
        &quot;readTime&quot;: &quot;A String&quot;, # Reads documents at the given time. This may not be older than 60 seconds.
      },
      &quot;readWrite&quot;: { # Options for a transaction that can be used to read and write documents. # The transaction can be used for both read and write operations.
        &quot;retryTransaction&quot;: &quot;A String&quot;, # An optional transaction to retry.
      },
    },
    &quot;readTime&quot;: &quot;A String&quot;, # Reads documents as they were at the given time. This may not be older than 270 seconds.
  }

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

      &quot;updateTime&quot;: &quot;A String&quot;, # Output only. The time at which the document was last changed. This value is initially set to the `create_time` then increases monotonically with each change to the document. It can also be compared to values from other documents and the `read_time` of a query.

For example, the structured field `&quot;foo&quot; : { map_value: { &quot;x&amp;y&quot; : { string_value: &quot;hello&quot; }}}` would be represented by the field path `foo.x&amp;y`. Within a field path, a quoted field name starts and ends with `` ` `` and may contain any character. Some characters, including `` ` ``, must be escaped using a `\`. For example, `` `x&amp;y` `` represents `x&amp;y` and `` `bak\`tik` `` represents `` bak`tik ``.

  <pre>Partitions a query by returning partition cursors that can be used to run the query in parallel. The returned partition cursors are split points that can be used by RunQuery as starting/end points for the query results.

Args:
  parent: string, Required. The parent resource name. In the format: `projects/{project_id}/databases/{database_id}/documents`. Document resource names are not supported; only database resource names can be specified. (required)
  body: object, The request body.
    The object takes the form of:

There are no ordering guarantees between sets of results. Thus, using multiple sets of results will require merging the different result sets. For example, two subsequent calls using a page_token may return: * cursor B, cursor M, cursor Q * cursor A, cursor U, cursor W To obtain a complete result set ordered with respect to the results of the query supplied to PartitionQuery, the results sets should be merged: cursor A, cursor B, cursor M, cursor Q, cursor U, cursor W

For example, if `partition_count` = 10 and `page_size` = 8, the first call to PartitionQuery will return up to 8 partitions and a `next_page_token` if more results exist. A second call to PartitionQuery will return up to 2 partitions, to complete the total of 10 specified in `partition_count`.
    &quot;partitionCount&quot;: &quot;A String&quot;, # The desired maximum number of partition points. The partitions may be returned across multiple pages of results. The number must be positive.
