1. What would you like to communicate to the user about this feature? Adds a new optional argument to the write() function, exclude_none . By default it is false. When it is set to true, empty values will not be written to the database. 2. Would you like the user to see examples of the syntax and/or executable code and its output? Yes, for example: schema = { "a" : int32(), "b" : int32()} b_data = [i for i in range(10)] * 2 b_data[2] = None data = Table.from_pydict( { "a" : [i for i in range(10)] * 2, "b" : b_data, }, ArrowSchema(schema), ) coll.drop() write(coll, data) col_data = list(coll.find({})) assert "b" in col_data[2] coll.drop() write(coll, data, exclude_none=True) col_data = list(coll.find({})) assert "b" not in col_data[2] 3. Which versions of the driver/connector does this apply to? PyMongoArrow 1.4
