I am building a rails application and I am currently hosting it on the Cedar stack on Heroku. The application has a postgres database and I am currently using the Heroku shared database. I understand the Heroku shared database is getting replaced soon.
My application's database is quite big and will have data added to it everyday. If I understood correctly the shared database replacement will allow you to have 10000 rows if you want to remain on the free option. My application will definitely have more than 10000 rows and I think it will fall in the next bracket of database size (the US$7 or US$9 per month).
Could someone clarify which database structure would be my next option if I exceed the 10000 rows maximum?
How do I configure my application to start using this database?
