Super interesting post. Would love to read more detail about their backup and restore infrastructure. If Tom and/or Shlomi are reading this: you mention taking multiple logical bac…

Author here. We use it because it works well for us. We've put a lot of work into making MySQL scale for us to the point where it's a very well supported system and one of the main…

In addition to what evanelias said, a logical dump also means we can load it into a MySQL instance running a different storage engine as well. In our case, it allows us to take a m…

Instance size varies a lot because we've got a lot of different MySQL workloads, some with very different configurations. Remember we're backing up each database separately though,…

We run a single mysqldump with --single-transaction for each database on the server, nothing special.

We take logical backups, not physical, and mysqldump is the best option for that. Having logical backups means we can do logical diffs as well (see https://youtu.be/Fe2oLZ4CWD4?t=9…

There's a few different ways to verify, a few of them involving stopping replication, like you pointed out. These can also sometimes be quite expensive, so depending on the type of…

This could be because Github's having issues with serving archives. See https://status.github.com/ EDIT: Should be working now

Out of curiosity, what do you use as an alternative to Word if you do have to open something in a .doc/.docx format? Surely just saying "I don't have Word because I'm a developer" …

Instead of pausing the feed, maybe a simple 'Load X new tweets' banner at the top of the feed would do a better job? Twitter actually does exactly this when loading new tweets on t…

The keypair AWS generates can only be downloaded once, at the time of instance creation. Beyond that, they expect you to be in possession of the keypair when launching another inst…

I am a Digital Ocean customer and the only password they've ever emailed me is the root password for the server I just bought. Arguably this isn't as safe as AWS' process of making…
