Genezzo-Contrib-Clustered 
=========================

Shared data cluster support for Genezzo

Basic routines inside Genezzo are overridden via Havok SysHooks.  Overridden
routines will (eventually) provide support for shared data clusters.  Routines
will provide transactions, distributed locking, undo and recovery.  Today
these routines support a single-user single-threaded database, and provide
basic transactional commit and rollback via undo.  Locking routines are
currently stubs.

INSTALLATION

To install this module type the following:

   perl Makefile.PL
   make
   make test
   make install

Note tests fail if prepared Genezzo database doesn't already exist.

To prepare for use of Genezzo::Clustered

  ./genprepundo.pl
  gendba.pl
  >@havok.sql
  >@syshook.sql
  >@clustered.sql

LIMITATIONS

  No Distrubuted/clustered functionality today.  Still single machine, 
  single process, single user, single threaded.

  This is pre-alpha software; don't use it to store any data you hope
  to see again!
