While I agree with you, "switch over to slave manually" just doesn't seem right. Who would monitor when to switch? Why would somebody want to monitor that? Havi

While I agree with you, "switch over to slave manually" just doesn't seem right. Who would monitor when to switch? Why would somebody want to monitor that? Having said that - there're probably solutions that allow switching when database is waiting for I/O
- pjc50 8y agoThey probably don't mean "manually" just "explicitly", as part of an automated failure detection process.
- tkyjonathan 8y agoRDS doesn't fail over to a slave anyway. You would need to do that manually. If you mean 'I ticked the multi-az box' that is only in the even that the AWS datacenter crashes - it will move RDS for you to another zone. If you have services that cache ip addresses from DNS, you will need to rediscover the database.
