RDS is more or less mysql 5.1, with a few goodies wrapped around it. they haven't (as far as i know) added any bells or whistles to the core database server - they've just automated the management of it.
my favourite goodies are point in time recovery and multi-availability zone with auto fail over. point in time recover is enabled by amazon taking snapshots of your database every 5 minutes or so. what's brilliant is that in just a few minutes you can boot one of these snapshots up as a completely functioning database server. so, for example, i was busy debugging something in our production environment earlier today so i just booted up a snapshot taken 5 minutes before and tested code against it. after i was done i terminated the instance and hence stopped paying for it. ok it cost a couple of dollars, but the sheer productivity gain is worth every penny. multi avail fail over is equally brilliant. switch it on and amazon maintain a fully functioning exact replica of your master database in a different availability zone, and have a mechanism to auto-failver if the master has any issues. it's basically mysql replication (master-slave) across 2 separate availability zones (ie. data centre) but fully automated. simon On 26 July 2010 22:00, Andrew Lindesay <a...@lindesay.co.nz> wrote: > Hi Simon; > > > ...amazon RDS for database server.. > > I see that's using MySQL –– does it somehow handle deferred referential > integrity checking? > > cheers. > > ___ > Andrew Lindesay > www.silvereye.co.nz > >
