Well I think Master/slave would do for the initial 'back-up' site, just to keep it up to date, although some day down the road load balancing sites might be a real solution for taming huge loads. >>For the driver spec, you will find the protocol specs in the >>org.continuent.sequoia.common.protocol.Commands class.

Sweet, I'll direct our developers that direction and see if they can get what they need out of that, thanks! >>I don't think there is any public documentation about the controller >>design.

Hopefully our guys are smart enough to get what they need out of the existing code. If they do release the docs, I know we'd be interested in checking them out. I think at this point we are thinking either A.) create 'upper middleware' that sites between clients and controllers for the purpose of replication or B.) Modify the controllers to do the job. Either way I will let you know how it goes. cheers Roy _______________________________________________ Sequoia mailing list [email protected] https://forge.continuent.org/mailman/listinfo/sequoia _______________________________________________ Sequoia mailing list [email protected] https://forge.continuent.org/mailman/listinfo/sequoia
