Prevayler backend partition type
--------------------------------

         Key: DIREVE-194
         URL: http://issues.apache.org/jira/browse/DIREVE-194
     Project: Directory Server
        Type: New Feature
    Reporter: Enrique Rodriguez
 Assigned to: Alex Karasulu 
    Priority: Minor


A Prevayler-based in-memory backend will save major disk IO down the line when 
used to replace the system backend partition.  All major subsystems that will 
be made more robust after subentries are implemented will most likely use the 
system partition to store persistent information.  Prevayler puts an entire db 
into memory, loading it on startup.  Right now the system partition parameters 
for JDBM are set to use as much cache as needed, which should result in similar 
behavior but in practice this has not proven to be the case.
