The locality features are huge. Being able to do database operations near where your users are is a big win for latency in global environments.

Pairing that with edge compute like fly.io is a killer combination. That you can use most of your normal Postgres libraries with it make it an easy transition.

I see, thanks. The uses for locality seem a little niche though no? Are the benefits that much greater that it would be noticeable to users?

You can see hundreds of ms of latency per request based purely on distance.

Tokyo - NYC is ~175 ms and that’s a good route. Compound that by all the requests you app does.
