Understanding N and 1 queries problem
We solved the N+1 queries problem where I work by raising the level of abstraction from "queries plus serialisation" to "what shape data is required". We open sourced the solution at https://www.django-readers.org/.

https://github.com/simonw/datasette-lite :
> You can use this tool to open any SQLite database file that is hosted online and served with a `access-control-allow-origin: ` CORS header. Files served by GitHub Pages automatically include this header, as do database files that have been published online using `datasette publish`.*
> [...] You can paste in the "raw" URL to a file, but Datasette Lite also has a shortcut: if you paste in the URL to a page on GitHub or a Gist it will automatically convert it to the "raw" URL for you
> To load a Parquet file, pass a URL to `?parquet=`

There are various *-to-sqlite utilities that load data into a SQLite database for use with e.g. datasette. E.g. Pandas with `dtype_backend='arrow'` saves to Parquet.
datasette plugins are written in Python and/or JS w/ pluggy:

[SQLlite] Is there any online SQL editor I can host on my website? Maybe something in JS or php
Datasette Lite might be even better for this - you can construct URLs that link directly to examples: https://github.com/simonw/datasette-lite

SQLite WASM Official
There are some amazing things for SQLite in the browser especially if you're looking for ways to host queryable data for cheap.
I have a hacked up POC experimental version of datasette-lite to be able to look at multi-GB databases at https://github.com/simonw/datasette-lite/pull/49. It uses a hacked up chunk'd lazyFile implementation from emscripten and others to grap pages from Cloudflare R2.
It's a test with california's unclaimed property records (https://www.sco.ca.gov/upd_download_property_records.html) of a 28GB searching up that guy who owns Twitter: https://datasette-lite-lab.mindflakes.com/index.html?url=htt...
I think there may be a space for super-large multi-GB files served from static storage being accessible from SQlite as well. Another one would be this full-text search of a 43GB SQLite database of Wikipedia's full text search: http://static.wiki/ . Hearing there's official support for this is awesome and I hope they also might add some provisions for those sticking with POSIX/Emscripten as well.

Hosting SQLite Databases on GitHub Pages
I grafted the enhanced lazyFile implementation of this to datasette-lite relatively recently. Threw in a 18GB CSV from
https://www.sco.ca.gov/upd_download_property_records.html
into a FTS5 Sqlite Database which came out to about 28GB after processing:
POC, non-merging Draft PR for the hack:
https://github.com/simonw/datasette-lite/pull/49
You can run queries through it if you URL hack into it and just get to the query dialog, browsing is kind of a dud at the moment since datasette runs a count(*) which downloads everything.

Datasette Lite: a server-side Python web application running in a browser
I have an open issue for that here: https://github.com/simonw/datasette-lite/issues/28
My initial hunch is that this will be really difficult - probably require a fork of something like https://github.com/coleifer/pysqlite3 then compiled for WebAssembly.
I'm confident it's feasible, but I don't have the skills to figure it out myself.
What are some alternatives?
