--------------------------------------------------

  
  == Under the hood ==
  
- Internally, when a partition is archived, a HAR is created using the files from the partition's
original location (e.g. {{{/warehouse/table/ds=1}}}). The parent directory of the partition
is specified to be the same as the original location and the resulting archive is named 'data.har'.
The archive is moved under the original directory (e.g. {{{/warehouse/table/ds=1/data.har}}})
and the partition's location is changed to point to the archive.
