             Summary: improve estimation of data byte size reading from source in ElasticsearchIO
                 Key: BEAM-8306
                 URL: https://issues.apache.org/jira/browse/BEAM-8306
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
    Affects Versions: 2.14.0
            Reporter: Derek He


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. But 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.
