For `map_value`, the field path is represented by the simple or quoted field names of the containing fields, delimited by `.`. For example, the structured field `"foo" : { map_value: { "x&y" : { string_value: "hello" }}}` would be represented by the field path `foo.x&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 `\`.

Fields
`fieldPath`	`string` (No description provided)

fieldPath

string

(No description provided)

FieldTransform

A transformation of a field of the document.

Fields
`appendMissingElements`	`object (ArrayValue)` Append the given elements in order if they are not already present in the current field value. If the field is not an array, or if the field does not yet exist, it is first set to the empty array. Equivalent numbers of different types (e.g. 3L and 3.0) are considered equal when checking if a value is missing. NaN is equal to NaN, and Null is equal to Null. If the input contains multiple equivalent values, only the first will be considered. The corresponding transform_result will be the null value.
`fieldPath`	`string` The path of the field. See Document.fields for the field path syntax reference.
`increment`	`object (Value)` Adds the given value to the field's current value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If either of the given value or the current field value are doubles, both values will be interpreted as doubles. Double arithmetic and representation of double values follow IEEE 754 semantics. If there is positive/negative integer overflow, the field is resolved to the largest magnitude positive/negative integer.
`maximum`	`object (Value)` Sets the field to the maximum of its current value and the given value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If a maximum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the larger operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The maximum of a zero stored value and zero input value is always the stored value. The maximum of any numeric value x and NaN is NaN.
`minimum`	`object (Value)` Sets the field to the minimum of its current value and the given value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the input value. If a minimum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the smaller operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The minimum of a zero stored value and zero input value is always the stored value. The minimum of any numeric value x and NaN is NaN.
`removeAllFromArray`	`object (ArrayValue)` Remove all of the given elements from the array in the field. If the field is not an array, or if the field does not yet exist, it is set to the empty array. Equivalent numbers of the different types (e.g. 3L and 3.0) are considered equal when deciding whether an element should be removed. NaN is equal to NaN, and Null is equal to Null. This will remove all equivalent values if there are duplicates. The corresponding transform_result will be the null value.
`setToServerValue`	`enum` Sets the field to the given server value.
Enum type. Can be one of the following:
`SERVER_VALUE_UNSPECIFIED`	Unspecified. This value must not be used.
`REQUEST_TIME`	The time at which the server processed the request, with millisecond precision. If used on multiple fields (same or different documents) in a transaction, all the fields will get the same server timestamp.

`structuredQuery`	`object (StructuredQuery)` A structured query. Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.

PartitionQueryResponse

The response for Firestore.PartitionQuery.

Fields

nextPageToken

string

A page token that may be used to request an additional set of results, up to the number specified by partition_count in the PartitionQuery request. If blank, there are no more results.

partitions[]

object (Cursor)

Partition results. Each partition is a split point that can be used by RunQuery as a starting or end point for the query results. The RunQuery requests must be made with the same query supplied to this PartitionQuery request. The partition cursors will be ordered according to same ordering as the results of the query supplied to PartitionQuery. For example, if a PartitionQuery request returns partition cursors A and B, running the following three queries will return the entire result set of the original query: * query, end_at A * query, start_at A, end_at B * query, start_at B An empty result may indicate that the query has too few results to be partitioned.

Fields

code

integer (int32 format)

The status code, which should be an enum value of google.rpc.Code.

Firestore guarantees a stable ordering through the following rules: * Any field required to appear in `order_by`, that is not already specified in `order_by`, is appended to the order in field name order by default. * If an order on `__name__` is not specified, it is appended by default. Fields are appended with the same sort direction as the last order specified, or 'ASCENDING' if no order was specified. For example: * `SELECT * FROM Foo ORDER BY A` becomes `SELECT * FROM Foo ORDER BY A, __name__` * `SELECT * FROM Foo ORDER BY A DESC` becomes `SELECT * FROM Foo ORDER BY A DESC, __name__ DESC` * `SELECT * FROM Foo WHERE A > 1` becomes `SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__`

The stream is guaranteed to send a `read_time` with `target_ids` empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not). For a given stream, `read_time` is guaranteed to be monotonically increasing.
`resumeToken`	`string (bytes format)` A token that can be used to resume the stream for the given `target_ids`, or all targets if `target_ids` is empty. Not set on every target change.
