sqlite-s3-query VS sqlite3vfshttp

Awesome project!

What about hosting the data in an S3 bucket with "Requestor Pays"? You'd only have the storage cost.

Disables anonymous access (so would a Dropbox share) but reduces your cost massively.

You wouldn't necessarily need an SQL frontend as it's readonly anyway, and there are multiple ways of letting SQLite access databases in S3 buckets, e.g. https://github.com/michalc/sqlite-s3-query

Aha! This is done in https://github.com/uktrade/mbtiles-s3-server, but using an alternative library to query SQLite on S3, https://github.com/michalc/sqlite-s3-query

(Full disclosure: I wrote most of both of these)

I was wondering how this ran queries against SQLite files in an S3 bucket. Here's the answer - it's using some very clever Python ctypes code to implement that HTTP Range header trick from last year:

https://github.com/michalc/sqlite-s3-query/blob/main/sqlite_...

Here's the inspiration for that: https://github.com/phiresky/sql.js-httpvfs

I'm a big fan of FTS5 as a cheap/easy way of adding full text search to datasets.

Recently I've been storing these datasets in S3 and been querying them directly via a VFS[0]. Its a simple way to have FTS available to lambda functions without the cost of using an online database.

You can also access sqlite databases directly from an http server that supports range requests (like s3). There are a bunch of implementations of this in different languages including Go[0] and Javascript[1].

There's a bunch of projects that have implemented this. I wrote a SQLite VFS in Go that lets you query a read-only SQLite db over http (including from s3) [0].

The VFS API offers the possibility for weirder storage solutions, if thats the type of thing you're into. Recently I've been moving some of my personal websites hosted on AWS Lambda over to use a read/write sqlite db backed by DynamoDB[1]. There are a bunch of limitations to this type of thing (like it uses a global write lock), but it works nicely for DBs that have low write frequency.

I just implemented something similar in Go[0]. Just yesterday I added the ability to compile it as a loadable sqlite3 extension, so you can use the normal sqlite3 cli tool to query databases hosted on an http(s) connection.
