Subject [jira] Created: (DIREVE-194) Prevayler backend partition type
Date Thu, 28 Jul 2005 17:08:22 GMT
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.
