Subject [jira] Created: (DERBY-512) enhance existing automatic space reclamation for tables
Date Wed, 17 Aug 2005 00:26:54 GMT
enhance existing automatic space reclamation for tables
-------------------------------------------------------

         Key: DERBY-512
         URL: http://issues.apache.org/jira/browse/DERBY-512
     Project: Derby
        Type: Improvement
  Components: Store  
    Reporter: Mike Matrigali
    Priority: Minor


The current space reclamation system does a good job of reusing space if inserts follow deletes
and if the 
deletes result in freeing complete pages.  In other cases unused space can grow in tables
and can only
be reclaimed by explicitly calling the compress table interfaces by hand.

As a zero admin database, derby should provide some way to automatically reclaim this space.
