      Implement a POC for filtering data to be cloned via the storage execution layer on the source side rather than the query layer for resharding

        • Create a filter for target documents and add ranges for index keys (most of this is done in POC)
        • Allow specifying this filter for queries (find)
          • Cursors already have a show recordID option
        • Filtering for record store
        • Filtering for sorted data interface
        • Test queries for both collection data and index data
        • Filter at a point in time

      Action Item:

        • Dust off skunkworks POC and get familiar with the implementation*
        • Squash commits and merge into fork of master*
