[jboss-dev-forums] [Design of JBoss Collaboration Server] - Re: JBMS Alternate Datastore

[csand101]

Thanks for the tip osterday.  Sequoia looks promising.  This is the type of functionality necessary to allow JBMS to be an HA solution.  In this case, it appears a MySQL cluster would not even be necessary as the updates are "multicast" to the db nodes at the Sequoia controler level.  Surely there is a performance cost there, as pointed out by Andrew, but there will be such a cost for any HA solution.  Don't get me wrong Andrew.  I'm excited for JBMS and would love to use it but in my situation there is no use for a fast mail server that can't be redundant.

The other solution could be to have each JBMS server use a db node which is in a MySQL cluster.  The MySQL cluster will keep data/mail in sync.  Load balancer in front of JBMS nodes or MX round-robin, as long as JBMS fails to handle the mail requests when it's jdbc connection is down so client can choose another MX or lb can choose another server.

Thanks all for the input.
