How Can I Deploy a Local MySQL Database to Heroku?

Deploying a Local MySQL Database to Heroku

As a developer new to Heroku, you may encounter challenges when attempting to utilize a MySQL database for your Ruby/Sinatra application. If you wish to avoid directly writing results to the Heroku-hosted database, opting to maintain your data locally, you have several options to consider:

1. PostgreSQL as a Local Data Store

Heroku natively supports PostgreSQL. Migrating your local database to Heroku will be more straightforward if you switch to PostgreSQL locally. Heroku provides documentation on importing and exporting PostgreSQL dump files, easing the data transfer process.

2. Converging MySQL and PostgreSQL

If MySQL is non-negotiable, there are two approaches to reconcile it with Heroku:

• Using the mysql2psql Gem: This method enables you to run MySQL locally and convert the database to PostgreSQL upon migrating to Heroku. Heroku provides detailed instructions on this process.
• Employing a MySQL Add-on: Heroku offers several third-party MySQL add-ons, such as ClearDB. These add-ons provide managed MySQL databases, allowing you to avoid the hassle of setting up and maintaining your own MySQL server.

Recommendation:

For optimal compatibility and ease of use, it is recommended to use PostgreSQL throughout your application. PostgreSQL integrates seamlessly with Heroku, making deployment and database management more efficient.
