pg-osc VS atlas

My thoughts exactly. It's surprising that external online schema change tools for Postgres have only become a thing fairly recently! The only two I'm aware of are:

* pgroll: Written in Golang, first commits June 2023. https://github.com/xataio/pgroll

* pg-osc: Written in Ruby, first commits Dec 2021. https://github.com/shayonj/pg-osc

Meanwhile over in the MySQL and MariaDB ecosystem, external OSC tools have been around for quite some time, starting with oak-online-alter-table over 15 years ago. The most popular options today are pt-online-schema-change or gh-ost, but other battle-tested solutions include fb-osc, LHM, and the latest entry Spirit.

Great to see more innovation in this space! How does this compare to?

Postgres has some less robust tooling, at least both of these carry the "experimental" tag:

But, still, they do it for you.

You can also try it out, Github: https://github.com/shayonj/pg-osc

This is very cool! I no longer work on Rails on daily basis, but would have loved to have this.

I built something similar called `pg-osc` / `pg-online-schema-change` for PostgreSQL workloads. It does zero downtime migrations using triggers and shadow table.

Also love that this is written in Ruby :). Going to check it out on some side projects.

(I'm one of the authors of this project).

fwiw, I personally am interested in this approach too[0]. I keep running into roadblocks around the ordering of events and some of the hairy issues around "destructive" actions (eg: renaming columns). i think we can get there, especially once we make progress with this LSP.

There are other notable mentions in this space:

Atlas: https://atlasgo.io/

Atlas: https://github.com/ariga/atlas. It can be integrated with any ORM, but also has an official one for GORM: https://atlasgo.io/guides/orms/gorm

Run the queryx db:create command to create a PostgreSQL database, and then run queryx db:migrate to automatically create the database migration files and database structure. Queryx’s database schema management is built upon Atlas.

In this case, I'd recommend you to check Atlas: https://github.com/ariga/atlas

My name is Rotem, I'm one of the creators of Atlas (https://atlasgo.io) a modern open-source schema management tool. Recently one of our engineers created a cool Django plugin that creates beautiful (in my eyes at least ;-)) and shareable ERDs from your Django data models.

Yes, there is: Atlas! https://atlasgo.io / https://github.com/ariga/atlas.

Hi there You should take a look at Atlas - https://atlasgo.io which can help your team in many aspects of CI/ CD for databases : * CI - detect (and prevent) risky / incorrect migrations automatically * CD - support for modern deployment infrastructure (terraform, helm, etc)

You might want to check out Atlas. It provides automatic migration planning for GORM, and has various guides on how deploying schema migration on the popular platform and tools, such as Helm, Kubernetes and ECS.
