+ #redirect Document_revisions
  == Overview ==
  
  CouchDB does not overwrite updated documents in place, instead it creates a new document
at the end of the database file, with the same `_id` but a new `_rev` identifier. This type
of storage system is space-wasteful so regular ["Compaction"] is needed to reclaim disk space.
Note that the older revisions are not available to ["Views"].
