That's a curious default choice. It's hard for me to imagine why you'd ever want to run RethinkDB on local instance storange, instead of EBS, given that EBS is much more reliable, is easier to back up, can be swapped between instances, etc. (Or is this AMI more for just trying out, not for actual production use?)
Obviously, EBS has its problems, but so does local instance storage.
Also: I remember that way-back-when, RethinkDB was touted as being designed for SSD's from the ground up. Is that still the case? Would running on provisioned-IOPS EBS provide a huge benefit over regular EBS or regular local storage?
AWS does have some SSD-based storage, but only for the larger instance types.
As I understand it, if you aren't using EBS, unless you snapshot your instances, they are reset to their last snapshot once they are shut down. Doesn't that seem like a huge risk to put your database under?
Are there good strategies for mirroring data onto EBS or running a slave instance or something?
