oxide VS sqlite-utils

Sorry about that, it's just a shortcut for https://github.com/fcoury/oxide.

Mostly on MongoDB to PostgreSQL translation server: http://oxidedb.com or https://demo.oxidedb.com.

I have been wanting to dive deep into a Rust project and the challenge of implementing the MongoDB protocol and then translating it into some sort of SQL counterpart was the first thing that really clicked and got me excited enough to get me working on it nonstop for 3 weeks now.

Some backstory:

I have created a product that relies on MongoDB for a document store but doesn’t really need any of the distributed features to really justify having a hosted MongoDB or DocumentDB instance. Now that we’re trying to turn this into a product, we’re seeing that some companies have a little bit of resistance around managing yet another database. Most of our clients already have and manage PostgreSQL in one form or another. I knew that PostgreSQL already offered first class JSON support, but I didn’t want to rewrite the application data layer from scratch if I could avoid it. That’s when I started researching if there was a “proxy” that would translate the MongoDB protocol - that I was completely ignorant about - into PostgreSQL. To my surprise there was nothing ready for production use but I found MangoDB that later on became FerretDB. I delved into the code and was in love with the idea. The team around is really nice, but I found that they had greater ambitions - they basically wanted to offer multiple backends, namely Tigris, on top of PostgreSQL.

On the other hand, I have been waiting to find an excuse to delve deeply into the rust ecosystem but never really found something I was passionate about until I had the idea of challenging myself to see if I could learn about the protocol that MongoDB uses by relying on their public documentation and the hints I found on FerretDB.

Another thing I added to my toolbelt while developing this was about creating parsers. In order to transform MongoDB JSON to SQL queries, I ported an existing library from the MongoDB team from PEG.js to pest.rs!

It’s in very early stages, and it’s work from someone that is not yet super comfortable with the stack so keep in mind this is the beginning of a journey for me that I embarked out of pure joy on getting a tiny bit better on rust and making things click internally.

So, his code might not be a good place to find best patterns (for ex, I don't think they are fully typed), but his repos are very pragmatic, and his development process is super insightful (well documented PRs for personal repos!). Best part, he blogs about every non-trivial update, so you get all the context!

Sounds like your problem is with SQLAlchemy, not with SQLite.

My https://sqlite-utils.datasette.io library might be a better fit for you. It's a much thinner abstraction than SQLAlchemy.

There are a few things you can do here.

SQLite is great at JSON - so I often dump JSON structures in a TEXT column and query them using https://www.sqlite.org/json1.html

I also have plugins for running jq() functions directly in SQL queries - https://datasette.io/plugins/datasette-jq and https://github.com/simonw/sqlite-utils-jq

I've been trying to drive the cost of turning semi-structured data into structured SQL queries down as much as possible with https://sqlite-utils.datasette.io - see this tutorial for more: https://datasette.io/tutorials/clean-data

This is also an area that I'm starting to explore with LLMs. I love the idea that you could take a bunch of messy data, tell Datasette Cloud "I want this imported into a table with this schema"... and it does that.

I have a prototype of this working now, I hope to turn it into an open source plugin (and Datasette Cloud feature) pretty soon. It's using this trick: https://til.simonwillison.net/gpt3/openai-python-functions-d...

I've baked a ton of different SQLite tricks - including things like full-text indexing support and advanced alter table methods - into my sqlite-utils CLI tool and Python library: https://sqlite-utils.datasette.io

My Datasette project provides tools for exploring, analyzing and publishing SQLite databases, plus ways to expose them via a JSON API: https://datasette.io

I've also written a ton of stuff about SQLite on my two blogs:

- https://simonwillison.net/tags/sqlite/

- https://til.simonwillison.net/sqlite

This is really fun. I have an experimental branch of my sqlite-utils CLI tool (which has dozens of sub-commands) running with this now and it really did only take 4 lines of code - I'm treating Trogon as an optional dependency because people using my package as a Python library rather than a CLI tool may not want the extra installed components:

There's an animated GIF demo of the result here: https://github.com/simonw/sqlite-utils/issues/545#issuecomme...

My project https://datasette.io/ is ideal for this kind of thing. You can use https://sqlite-utils.datasette.io/ to load JSON data into a SQLite database, then publish it with Datasette.

I've been using this for about six months now and I absolutely love it.

Make never stuck for me - I couldn't quite get it to fit inside my head.

Just has the exact set of features I want.

Here's one example of one of my Justfiles: https://github.com/simonw/sqlite-utils/blob/fc221f9b62ed8624... - documented here: https://sqlite-utils.datasette.io/en/stable/contributing.htm...

I also wrote about using Just with Django in this TIL: https://til.simonwillison.net/django/just-with-django

SQLite with the open source toolchain I've been building over the past five years:

https://datasette.io as the interface for running queries against (and visualizing) my data.

https://sqlite-utils.datasette.io/ as a set of tools for creating and modifying my databases (inserting JSON or CSV data, enabling full text search text)

https://dogsheep.github.io as a suite of tools for importing my personal data - see also this talk I gave about that project: https://simonwillison.net/2020/Nov/14/personal-data-warehous...

Here's an example: https://github.com/simonw/sqlite-utils/pull/468

> After identifying about 7 commits (with pretty basic/useless messages, and no PR link!), I then had to find the corresponding PRs based on timestamps, and search the PR history for PRs merged around those timestamps.

Not sure if this would save any time, but it is possible to search PRs by commit. For example, say git blame led me to this commit: https://github.com/simonw/sqlite-utils/commit/129141572f249e...

I could have found PR #373 via this search: https://github.com/simonw/sqlite-utils/pulls?q=bb16f52681b6d...

> I thus treat PRs as ephemeral

I think I see what you're saying but as others have pointed out, sometimes you want to add screenshots etc to the context, and you can't capture this kind of info in commit messages. So then you have two choices: issues or PRs.

> Then any review comments are preferably not addressed directly in the PR

I would think that sometimes you really do want to have a back and forth conversation in the PR, rather than just a "make this change" -> "ok done" type of feedback loop.

I view the PR as an decent place for all of this because it's basically a commit of commits, capturing the related changes/conversation/context all in a single place at the point of merge.
