The key here is to make a single API call to the backend which then runs 100+ SQL queries at once and combines the results into a single JSON response - that way you're only paying the network cost once.

See https://www.sqlite.org/np1queryprob.html

I've implemented GraphQL on top of SQLite and found it to be an amazingly good match, because the biggest weakness of GraphQL is that it makes it easy to accidentally trigger 100s of queries in one request and with SQLite that really doesn't matter.

FYI: We're offering a SQLite hosting service which automatically creates a full-fledged GraphQL endpoint for your database: https://www.airsequel.com

that doesn't eliminate need for loading states at all, and is already solved by things like react server components or remix (see waterfall removal graphic https://remix.run/)

i think this discussion is confusing the use of sqlite in local-first apps, where there's no loading states because the database is in the browser. you can use sqlite on your server, but you still need a "loading state".

even with postgres, if your data and server are colocated, the time between the 2 is already almost 0

now maybe the argument is your servers are deployed globally each with an sqlite db. that's not all that different from global postgres read replicas

If the data and the server are colocated on the same machine, the database network overhead is almost zero. But that's not necessarily true otherwise. For an HTTP request that incurs a single query, you can round it to zero, but you have to be careful not to write request handlers that incur lots of queries if you're trying to stay below the 100ms threshold.

Could you give a pointer to the repository, or is this part of Datasette?

[rapnie]

Nevermind, found it. Just don't know the license.

It's Apache 2 (there is a badge in the README) but I realize now I forgot to drop a copy of the license into the repo - fixing that now.
