ormDB + Sequelize

What This Adapter Will Do

ormDB is a relational database engine written in Rust that replaces PostgreSQL, MySQL, and SQLite as the actual database underneath your application. The planned @ormdb/sequelize-adapter package will connect Sequelize’s model system and association layer to ormDB, letting you keep your existing model definitions and eager loading patterns while the database resolves object graphs natively.

Sequelize’s include option on findAll and findOne tells the ORM which associated models to load. With a SQL database, Sequelize generates complex JOIN queries or issues multiple SELECT statements. The ormDB adapter will translate these into native graph-fetch requests, resolving the entire association tree in a single round-trip and eliminating N+1 queries.

Planned Setup

The adapter will follow the same pattern as other ormDB ORM adapters:

npm install @ormdb/sequelize-adapter

import { Sequelize } from 'sequelize'
import { OrmDBDialect } from '@ormdb/sequelize-adapter'

const sequelize = new Sequelize({
  dialect: OrmDBDialect,
  host: process.env.ORMDB_HOST,
  port: Number(process.env.ORMDB_PORT),
  database: process.env.ORMDB_DATABASE,
})

Your existing models and queries will work unchanged:

const users = await User.findAll({
  include: [
    {
      model: Post,
      include: [Comment, Tag],
    },
  ],
})

What Will Change, What Will Stay

Stays the same: Model definitions (define), associations (hasMany, belongsTo, belongsToMany, hasOne), finders (findAll, findOne, findByPk), eager loading via include, scopes, and hooks.

Changes: The database engine. Nested include trees become single-round-trip graph fetches. Migrations gain A-D safety grading. Vector search, geo search, full-text search, and change streams become available natively.

Removed: Raw SQL via sequelize.query() and Sequelize.literal(). All queries must use Sequelize’s model-based API.
