> ElasticsearchIO splits BoundedSource based on the Elasticsearch index size.
> We expect it can be more accurate to split it base on query result size.
> Currently, we have a big Elasticsearch index. But for query result, it only
> contains a few documents in the index. ElasticsearchIO splits it into up
> to1024 BoundedSources in Google dataflow. It takes long time to finish the
> processing the small numbers of Elasticsearch document in Google dataflow.
