How to deploy local MySQL database to Heroku

I’m new to using Heroku and I have a Ruby/Sinatra app in which I plan on using a MySQL database as the main data store.

However, I do not want to write results directly to the database on Heroku. Instead, I want to write the results to a local database, and then be able to easily deploy/update/copy my local DB to the “production” database on Heroku.

How do I do this?

However my recommendation would be to use postgres end to end, as it is baked into Heroku, and you’ll be working with the default ways of using Heroku, not against them.

Postgres is very good too!
