Fields
Union field `value_type`. Must have a value set. `value_type` can be only one of the following:
`nullValue`	`null` A null value.
`booleanValue`	`boolean` A boolean value.
`integerValue`	`string (int64 format)` An integer value.
`doubleValue`	`number` A double value.
`timestampValue`	`string (Timestamp format)` A timestamp value. Precise only to microseconds. When stored, any additional precision is rounded down. A timestamp in RFC3339 UTC "Zulu" format, accurate to nanoseconds. Example: `"2014-10-02T15:01:23.045123456Z"`.
`stringValue`	`string` A string value. The string, represented as UTF-8, must not exceed 1 MiB - 89 bytes. Only the first 1,500 bytes of the UTF-8 representation are considered by queries.
`bytesValue`	`string (bytes format)` A bytes value. Must not exceed 1 MiB - 89 bytes. Only the first 1,500 bytes are considered by queries. A base64-encoded string.
`referenceValue`	`string` A reference to a document. For example: `projects/{project_id}/databases/{database_id}/documents/{document_path}`.
`geoPointValue`	`object(LatLng)` A geo point value representing a point on the surface of Earth.
`arrayValue`	`object(ArrayValue)` An array value. Cannot directly contain another array value, though can contain an map which contains another array.
`mapValue`	`object(MapValue)` A map value.

MapValue

A map value.

Fields

Fields
`fields`	`map (key: string, value: object(Value))` The map'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 map keys, represented as UTF-8, must not exceed 1,500 bytes and cannot be empty. An object containing a list of `"key": value` pairs. Example: `{ "name": "wrench", "mass": "1.3kg", "count": "3" }`.
