参考：https://elasticsearch-py.readthedocs.io/en/master/helpers.html#elasticsearch.helpers.bulk

def gendata():
    mywords = ['foo', 'bar', 'baz']
    for word in mywords:
        yield {
            "_index": "mywords",
            "_type": "document",
            "doc": {"word": word},
        }

res_tuple = helpers.bulk(es, gendata())

res_tuple

Helper for the bulk() api that provides a more human friendly interface - it consumes an iterator of actions and sends them to elasticsearch in chunks. It returns a tuple with summary information - number of successfully executed actions and either list of errors or number of errors if stats_only is set to True. Note that by default we raise a BulkIndexError when we encounter an error so options like stats_only only apply when raise_on_error is set to False.
