Is flyway database agnostic in its support for multiple databases?

Question

Is Flyway suitable for implementation in an application that will support multiple databases?

We don't know what our customers are using - could be either MySQL, Postgres or Oracle. Can we still use Flyway to migrate the database for new versions of the application?

Answer 1

if your question is: does Flyway provide a DDL abstraction layer across the databases it supports, the answer is no.

This was a conscious design decision, to make sure the full power of the underlying database is available and not just the smallest common denominator supported by the migration tool.

For your use case, you could either provide different migration scripts for the different databases. They should be very similar though.

If you do not wish to potentially duplicate the migration scripts and can live with the smallest common denominator approach, have a look at LiquiBase which might be a better fit for your usecase (if you can live with the XML)
