How can I deploy my local MySQL database to Heroku?

Deploying Local MySQL Database to Heroku

Integrating a MySQL database into a Heroku-deployed Ruby/Sinatra application can be challenging for those unfamiliar with the platform. This walkthrough addresses the specific requirement of writing results to a local database while deploying them to Heroku's production environment.

Recommended Approach:

Rather than maintaining a local MySQL database, it is highly recommended to use PostgreSQL, which is Heroku's native database. This streamlines the deployment process by avoiding the need for database conversion. Heroku provides convenient import/export functionality for PostgreSQL dump files, ensuring a seamless data transfer between local and production environments.

Alternative Options for MySQL Integration:

If adherence to MySQL is necessary, two options are available:

1. Convert to PostgreSQL using mysql2psql: Utilize the mysql2psql gem to convert your local MySQL database to PostgreSQL during the Heroku migration.
2. Employ a MySQL addon: Opt for a MySQL addon such as ClearDB, which provides a managed MySQL database service on Heroku.

Benefits of Using PostgreSQL:

Ultimately, using PostgreSQL throughout the development process aligns with Heroku's default configurations, simplifying your deployment experience. PostgreSQL offers a robust feature set and is a widely adopted database, ensuring support and compatibility with your application.
