Field mapping portion of "fl" should be handled in the merger node

    XMLWordPrintableJSON

    Details

      Description

      Today "fl" is used for
      a) filtering the fields and
      b) mapping the field names to alternate names.

      we should optimize the network traffic by not passing the field mappings to all the nodes and run on the node which is fanning-out and merging the request.

      This impacts the network in the cases where there are 100s of shards to send and the field mapping list is huge
