      Description

      Hourly and Daily rolling are currently done using a M/R but all spill files are already sorted so it's just a Merged sort.
      Doing that from a standalone application will be more efficient than using a M/R.

      Another way to implement this will be to take advantage of the latest version of Pig (multiple queries optimization) and do the rolling once a day at the same time as we are computing daily metrics (Since the data has already been loaded by pig).

          Are we talking only about rolling the post-demux records, or also the raw chunks?
          Being able to archive chunks is a fairly high priority for me. See CHUKWA-317.
