  == Database Compaction ==
  
- Compaction rewrites the database file, removing outdated document revisions and deleted
documents. It is available in builds of CouchDB built from SVN after 2008-04-07, and in official
release since version 0.8-incubating.
+ Compaction rewrites the database file, removing outdated document revisions and deleted
documents. Outdated revisions are revisions of documents which are not needed anymore for
conflict resolution. Technically compaction only makes these documents (their content or body)
unavailable and leaves a skeleton for conflict resolution during [[Replication|replication]].
It is available since version 0.8-incubating.
  
  Compaction is manually triggered per database. Support for queued compaction of multiple
databases is planned. Please note, that compaction will be run as a background task.
