Bish f77b2525a5 Additional fix for: https://issues.apache.org/jira/browse/AMQ-3775 On remove of inner ListNode entries the Iterator remove was not properly setting the Next page Id for the previous node leading to the iterator not being able to traverse the entire list correctly. git-svn-id: https://svn.apache.org/repos/asf/activemq/trunk@1328739 13f79535-47bb-0310-9956-ffa450edef68		2012-04-21 21:57:31 +00:00

=======================================================================
 KahaDB : An Embedded Lightweight Non-Relational Database
=======================================================================

Goals:
  * Provide a simple collections based interface for storing persistent
    data.
  * Provide a lower level key value interface for storing data. Secondary
    keys should be supported.
  * Fast recovery

Status:
  * Moved the org.apache.activemq.kaha package into this module
    and renamed it as org.apache.kahadb
  * Moved a refactored version of the low level indexing logic
    used by Apache xindice to the org.apache.kahadb.xindice page.
  
TODO:
  * None of our current index support fast recovery.  They suffer
    from partial page write failures so on a crash, they have
    to be fully rebuilt from the data logs.
  * Indexes should know what the last transaction id that updated
    it, so that missing operations can be replayed. 
  * Investigate implementing data log replication for HA.
