Description

__init__.__doc__

Create an UpdateMany instance.

        For use with :meth:`~pymongo.collection.Collection.bulk_write`.

        :Parameters:
          - `filter`: A query that matches the documents to update.
          - `update`: The modifications to apply.
          - `upsert` (optional): If ``True``, perform an insert if no documents
            match the filter.
          - `collation` (optional): An instance of
            :class:`~pymongo.collation.Collation`. This option is only
            supported on MongoDB 3.4 and above.
          - `array_filters` (optional): A list of filters specifying which
            array elements an update should apply. Requires MongoDB 3.6+.
          - `hint` (optional): An index to use to support the query
            predicate specified either by its string name, or in the same
            format as passed to
            :meth:`~pymongo.collection.Collection.create_index` (e.g.
            ``[('field', ASCENDING)]``). This option is only supported on
            MongoDB 4.2 and above.
