We use Flyway in a number of ways. Scripted as part of some deployment processes, included with Spring Boot applications for a RoR style migration on boot, and actually use it in Java code to manage other databases from our application during runtime. An interesting way to use it is that you can have multiple applications that may use the same schema but are responsible for their own tables- you can specify a different schema metadata table for each application and they can generally live together fairly happily. We also have an application that 'deploys' data to target databases, so we are able to run Flyway via their Java library to make sure the target schemas are correct before running our statements against them. Prior to Flyway I used Liquibase, which is also pretty powerful- but Flyway has just been so much more versatile- and the Spring Boot 'auto' integration has been awesome.
