# sequelize-cockroachdb

[This NPM package](https://www.npmjs.com/package/sequelize-cockroachdb) makes Sequelize compatible with CockroachDB.

[Learn how to build a Node.js app with CockroachDB.](https://www.cockroachlabs.com/docs/stable/build-a-nodejs-app-with-cockroachdb-sequelize.html)

Please file bugs against the [sequelize-cockroachdb project](https://github.com/cockroachdb/sequelize-cockroachdb/issues/new)

## Requirements

This package needs Node.js v12 or later

## Setup and run tests

First make sure you have CockroachDB installed. You can run `cockroach version` to see if is installed or you can [download here](https://www.cockroachlabs.com/docs/stable/install-cockroachdb.html)

Run `cockroach start-single-node --insecure --logtostderr` to start the database. If this returns `ERROR: cockroach server exited with error: unable to lookup hostname` run with `--host localhost` flag.

Run `cockroach sql --insecure` to enter in SQL mode and type `CREATE DATABASE sequelize_test;`

Then install the depedencies with `npm i` and `npm test` to run all tests

## Limitations

### Dealing with transactions

From the [docs](https://www.cockroachlabs.com/docs/stable/transactions.html)

> CockroachDB guarantees that while a transaction is pending, it is isolated from other concurrent transactions with serializable isolation.

Which means that any other query made in another connection to the same [node](https://www.cockroachlabs.com/blog/how-cockroachdb-distributes-atomic-transactions/) will hang.

For example:
```js
const t = await this.sequelize.transaction();
await this.User.create({ name: "bob" }, { transaction: t });
await this.User.findAll({ transaction: null }); // Query will hang!
```

### CockroachDB does not support yet:

- [CITEXT](https://github.com/cockroachdb/cockroach/issues/22463)
- [TSVector](https://github.com/cockroachdb/cockroach/issues/41288)
- [lower](https://github.com/cockroachdb/cockroach/issues/9682?version=v20.2) function for index

See `tests/model_create_test.js` to browse those implementations.
