I can't think of any project I've worked on where the main data base could be backed up and restored to a different database in "2 minutes"

The sarcasm was warranted.

With SSO multi-account and 2FA, it'd probably take longer than 2 minutes just to authenticate and configure AWS correctly to get started.

Isn’t the suggestion that the “active work” is very little and most of the time you’re just waiting?

Well, the elapsed time is how long I need production to be offline so there are a few more people "just waiting"

Sure, but you don’t really expect to swap databases with a huge data store without any downtime, do you? I’m not aware of any technology that makes that easy.

Then why are you defending the ridiculous "2 minute" thing?

If the CEO asked how long a migration will take would you respond "2 minutes of engineering time"?

In that situation I would guess the one-click tool doesn’t really handle everything you’d need either so I don’t get what the point of the comparison is.

I’m not the person would said it was two minutes.

Nor am I but if we go back up the claim was that they were making it much easier to get in than get out, but unless you're telling me that the one-click tool somehow solves all the issues of migrating a large production database that's in use the difference between the two is a minuscule amount of active work.

If you were the CEO and your engineer and someone said, "2 minutes of actual work and a lot of waiting around due to the limitations of the hardware", would you interpret that as "2 minutes of engineering time"?

Obviously I'm going to spend a lot more time communicating the details of the situation to the CEO of a company that is paying me, than I'm going to spend communicating in a Hacker News comment. But as it turns out, no amount of communication is going to be effective if people don't bother to read past the first opportunity they see to jump in with a correction, even if that means stopping reading mid-sentence.

Why would you take production offline to swap databases? Elapsed time is how long you need to run the new database alongside the old one.

This whole thread is about incompatible databases. If you know a 2 minute solution to a live transfer in that situation I’m all ears.

If only you had read the whole sentence, you might have saved yourself a bit of righteous anger.

I think you've failed to consider how impractical even doing a SQL dump can be on a large-ish database, forget about the reloading time.

I haven't failed to consider that, you've just failed to read where I explicitly mentioned that.

Consider: is that impracticality caused by Amazon creating vendor lock-in? Or is that impracticality caused by the fact that reading terabytes of data from storage, transferring it over the network, and writing it into storage is inherently slow because of the physical limitations of hardware, no matter what vendor you're using?

It's a bit odd for me to be in the position of defending Amazon here. I genuinely don't like them, don't use them, and generally do think they're guilty of creating a lot of vendor lock-in. But this is legitimately not an example of any of that.

I didn't miss where you mentioned it. I missed where you considered it. As in, you know, gave any thought to the practicalities involved.

You're really claiming you can read my mind to know what I have and have not considered right now, despite me bringing it up specifically. Alrighty then.

I'm simply going by what you've written here. If you have considered it, then you have not "shown your work," so to speak.

And if I were being graded that would matter.

As is, I've no responsibility to show you anything, and you're just making unwarranted assumptions about what I have and haven't considered, based on a pretty selective reading of what I've said.

You seem to be the one angry here.

I'm not sure what I was supposed to take away from your cryptic sentence. Is there a two minute solution to this problem that you are smugly keeping to yourself so you can mock people replying to you?

My guy, read this whole sentence, which has remained unchanged this entire conversation:

"There's no way to move from Aurora to RDS short of... 2 minutes of actual work and a lot of waiting around due to the limitations of the hardware?"

You seem to be having trouble getting past the word "and", so I've helpfully italicized the part you've repeatedly missed or ignored.

Now sure, that's a bit vague, but if you want more details it might have been advisable to ask a question rather than simply ignoring half the sentence because you don't understand it and jumping in with a correction.

And honestly, even if it's vague on some details, there's no universe in which "2 minutes and a lot of waiting around" = "2 minutes". Whatever vagueness you might accuse me of, that fact isn't vague.

hey,

that is fair answer! AFAIK, there are two things that consider:

* Aurora do have some vendor-locking feature if I'm not wrong?

* moving from Aurora to PostGres will lead to downtime of 2 minutes + unknown waiting, where this is not a case when you convert from PostGres to Aurora.
