Hi, RabbitMQ supports transactions, via the TX class. You just need to use a version recent enough. In Landscape, we don't use commits for publishing, and send the messages after database commits, to make sure the rows are there. There is of course a window where publishing can fail, but we would need to use 2pc to take advantage of it, I think. -- Thomas _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
