     * Equivalent to `method.name.toCamelCase()`, but returns a NodeJS Stream object.
     * @param {Object} request
     *   The request object that will be sent.
     * @param {string} request.parent
     *   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.
     * @param {google.firestore.v1.StructuredQuery} request.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.
     * @param {number} request.partitionCount
     *   The desired maximum number of partition points.
     *   The partitions may be returned across multiple pages of results.
     *   The number must be positive. The actual number of partitions
     *   returned may be fewer.
     *
     *   For example, this may be set to one fewer than the number of parallel
     *   queries to be run, or in running a data pipeline job, one fewer than the
     *   number of workers or compute instances available.
     * @param {string} request.pageToken
     *   The `next_page_token` value returned from a previous call to
     *   PartitionQuery that may be used to get an additional set of results.
     *   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
     * @param {number} request.pageSize
     *   The maximum number of partitions to return in this call, subject to
     *   `partition_count`.
     *
     *   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`.
     * @param {object} [options]
     *   Call options. See {@link https://googleapis.dev/nodejs/google-gax/latest/interfaces/CallOptions.html|CallOptions} for more details.
     * @returns {Stream}
     *   An object stream which emits an object representing [Cursor]{@link google.firestore.v1.Cursor} on 'data' event.
     *   The client library will perform auto-pagination by default: it will call the API as many
     *   times as needed. Note that it can affect your quota.
     *   We recommend using `partitionQueryAsync()`
     *   method described below for async iteration which you can stop as needed.
     *   Please see the
     *   [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination)
     *   for more details and examples.
