🔄 Prisma vs Kysely: Unordered Migrations Comparison

📋 Executive Summary

Prisma does not suffer from the same unordered migrations problem that affects Kysely. While Kysely strictly enforces alphabetical/chronological ordering of migrations and fails when migrations are executed out of order, Prisma uses a more flexible approach that tracks migration history in the database and provides tools to handle divergent migration histories.

⚠️ The Kysely Problem

Kysely Migration Ordering: Handling Parallel Development

The Problem

When multiple developers work on feature branches simultaneously, they often create migrations with timestamps that become out of order when merged. This is a common scenario:

• Developer A creates migration 20240112_1200_add_users.sql on their feature branch
• Developer B creates migration 20240112_1201_add_products.sql on their feature branch
• Developer B merges first, production runs the 12:01pm migration
• Developer A merges second, but now there's a problem...

You don't really need Homebrew

[pkgx][pkgx] is a package manager that can basically do everything Homebrew can.

You can find full installation instructions [here][pkgx-install], but it's simplest to run:

curl -fsS https://pkgx.sh | sh
