How Balanced does Database Migrations with Zero-Downtime. I’m fascinated by the idea of “pausing” traffic during a blocking site maintenance activity (like a database migration) and then un-pausing when the operation is complete—so end clients just see some of their requests taking a few seconds longer than expected. I first saw this trick described by Braintree. Balanced wrote about a neat way of doing this just using HAproxy, which lets you live reconfigure the maxconns to your backend down to zero (causing traffic to be queued up) and then bring the setting back up again a few seconds later to un-pause those requests.
