    - `updateMask` DocumentMask — 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.
      - `fieldPaths` string[] — The list of field paths in the mask. See Document.fields for a field path syntax reference.
    - `delete` string — A document name to delete. In the format: `projects/{project_id}/databases/{database_id}/documents/{document_path}`.
    - `update` Document — A Firestore document. Must not exceed 1 MiB - 4 bytes.
      - `createTime` string, google-datetime — Output only. The time at which the document was created. This value increases monotonically when a document is deleted then recreated. It can also be compared to values from other documents and the `read_time` of a query.
      - `updateTime` string, google-datetime — 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.
      - `fields` object — The document's fields. The map keys represent field names. Field names matching the regular expression `__.*__` are reserved. Reserved field names are forbidden except in certain documented contexts. The field names, represented as UTF-8, must not exceed 1,500 bytes and cannot be empty. Field paths may be used in other contexts to refer to structured fields defined here. For `map_value`, the field path is represented by a dot-delimited (`.`) string of segments. Each segment is either a simple field name (defined below) or a quoted field name. For example, the structured field `"foo" : { map_value: { "x&y" : { string_value: "hello" }}}` would be represented by the field path `` foo.`x&y` ``. A simple field name contains only characters `a` to `z`, `A` to `Z`, `0` to `9`, or `_`, and must not start with `0` to `9`. For example, `foo_bar_17`. A quoted field name starts and ends with `` ` `` and may contain any character. Some characters, including `` ` ``, must be escaped using a `\`. For example, `` `x&y` `` represents `x&y` and `` `bak\`tik` `` represents `` bak`tik ``.
      - `name` string — The resource name of the document, for example `projects/{project_id}/databases/{database_id}/documents/{document_path}`.
    - `updateTransforms` FieldTransform[] — The transforms to perform after update. This field can be set only when the operation is `update`. If present, this write is equivalent to performing `update` and `transform` to the same document atomically and in order.
      - `fieldPath` string — The path of the field. See Document.fields for the field path syntax reference.
      - `setToServerValue` 'SERVER_VALUE_UNSPECIFIED' | 'REQUEST_TIME' — Sets the field to the given server value.
