• A MySQL compatible database engine written in pure Go

  Hi, this is my project :)

  For us this package is most important as the query engine that powers Dolt:

  https://github.com/dolthub/dolt

  We aren't the original authors but have contributed the vast majority of its code at this point. Here's the origin story if you're interested:

• The Great Migration from MongoDB to PostgreSQL

  It's a pretty good default stance, yeah.

  We have been trying to convince people to use our new database [1] for several years and it's an uphill battle, because Postgres really is the best choice for most people. They really have to need our unique feature (version control) to even consider it over Postgres, and I don't blame them.

• What I Talk About When I Talk About Query Optimizer (Part 1): IR Design
  7 projects | news.ycombinator.com | 29 Jan 2024

  We implemented a query optimizer with a flexible intermediate representation in pure Go:

  https://github.com/dolthub/go-mysql-server

  Getting the IR correct so that it's both easy to use and flexible enough to be useful is a really interesting design challenge. Our primary abstraction in the query plan is called a Node, and is way more general than the IR type described in the article from OP. This has probably hurt us: we only recently separated the responsibility to fetch rows into its own part of the runtime, out of the IR -- originally row fetching was coupled to the Node type directly.

  This is also the query engine that Dolt uses:

  https://github.com/dolthub/dolt

  But it has a plug-in architecture, so you can use the engine on any data source that implements a handful of Go interface.

• Show HN: DoltgreSQL – Version-Controlled Database, Like Git and PostgreSQL
  7 projects | news.ycombinator.com | 1 Nov 2023

  Just want to point out that we're announcing development on the project. It's absolutely not ready for mainstream use yet! We have Dolt (https://github.com/dolthub/dolt) which is production-ready and widely in use, but it uses MySQL's syntax and wire protocol. We are building the Dolt equivalent for PostgreSQL, which is DoltgreSQL, but it's only pre-alpha.

• Pg_branch: Pre-alpha Postgres extension brings Neon-like branching
  6 projects | news.ycombinator.com | 1 Oct 2023

  Interesting that branching is now better supported and almost free. I wonder if merging can be simplified or whether it already is as simple and as fast as it can be?

  I guess I am inspired by Dolt’s ability to branch and merge: https://github.com/dolthub/dolt

• SQLedge: Replicate Postgres to SQLite on the Edge

  #. SQLite WAL mode

  From https://www.sqlite.org/isolation.html https://news.ycombinator.com/item?id=32247085 :

  > [sqlite] WAL mode permits simultaneous readers and writers. It can do this because changes do not overwrite the original database file, but rather go into the separate write-ahead log file. That means that readers can continue to read the old, original, unaltered content from the original database file at the same time that the writer is appending to the write-ahead log

  #. dolthub/dolt: https://github.com/dolthub/dolt

  > Dolt can be set up as a replica of your existing MySQL or MariaDB database using standard MySQL binlog replication. Every write becomes a Dolt commit. This is a great way to get the version control benefits of Dolt and keep an existing MySQL or MariaDB database.

  #. Ibis + Substrait [ + DuckDB ]

  > ibis strives to provide a consistent interface for interacting with a multitude of different analytical execution engines, most of which (but not all) speak some dialect of SQL.

  > Today, Ibis accomplishes this with a lot of help from `sqlalchemy` and `sqlglot` to handle differences in dialect, or we interact directly with available Python bindings (for instance with the pandas, datafusion, and polars backends).

  > [...] `Substrait` is a new cross-language serialization format for communicating (among other things) query plans. It's still in its early days, but there is already nascent support for Substrait in Apache Arrow, DuckDB, and Velox.

  #. benbjohnson/postlite: https://github.com/benbjohnson/postlite

  > postlite is a network proxy to allow access to remote SQLite databases over the Postgres wire protocol. This allows GUI tools to be used on remote SQLite databases which can make administration easier.

  > The proxy works by translating Postgres frontend wire messages into SQLite transactions and converting results back into Postgres response wire messages. Many Postgres clients also inspect the pg_catalog to determine system information so Postlite mirrors this catalog by using an attached in-memory database with virtual tables. The proxy also performs minor rewriting on these system queries to convert them to usable SQLite syntax.

  > Note: This software is in alpha. Please report bugs. Postlite doesn't alter your database unless you issue INSERT, UPDATE, DELETE commands so it's probably safe. If anything, the Postlite process may die but it shouldn't affect your database.

  If you are just looking for data versioning there is Dolt:

  https://github.com/dolthub/dolt

  And that has a user-friendly UI in DoltHub:

  You wouldn't store the images themselves in Dolt, those would likely be links to S3 but al the labels and surrounding metadata could be stored in Dolt?
