Date Wed, 03 Mar 2010 22:35:48 GMT
Dear Wiki user,

The "Compaction" page has been changed by SebastianCohnen.

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

  
  == Database Compaction ==
  
- Compaction rewrites the database file, removing outdated document revisions and deleted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 Outdated revisions are revisions of documents which are not needed anymore for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.

documents. Outdated revisions are revisions of documents which are currently not in a conflict
state on the particular node the compaction is running on. Technically compaction only makes

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.
