I've successfully set up a drupal-clean test build on my Ubuntu 19.04 machine using buildkit, amp config and amp test and chose mysql_ram_disk rather than mysql_dsn.

My intent was to have a semi-permanent dev environment.

Did I make the wrong choice? Should I use mysql_ram_disk for such an environment?

It's a little bit hard to answer without more info but generally the ram disk isn't going to save your data unless you do something extra, so it's more useful for one-off tests or something where you need speed over permanence, like running unit tests (which it mentions in the readme). I don't use buildkit since I'm on windows but I do switch over to a ramdisk when running tests since it's way faster when it keeps needing to load/reset the database. I wouldn't recommend a ramdisk for setting up a semi-permanent dev environment that you plan to work on regularly, unless you're willing to regularly dump the data somewhere and reload it later, or automate that at startup/shutdown, and risk losing something in the middle.

  • right so the ram_disk is loaded into ram and disappears when I shut my machine down. Duh on me. So, I made the wrong choice, since my goal is a semi-permanent dev environment. Back to amp config set up. Thanks! Sep 10, 2019 at 22:36
