In this episode, we introduce the Flyway database migration script library and it’s integration with Spring Boot. In previous episodes of the Spring Data Fundamentals series, we showed you how to initialize a database using Spring JDBC “schema” and “data” initialization scripts. In this episode you will learn how to use the Flyway library to not only initialize an empty database, but to automatically upgrade the database as new versions of your application are released.
Your voice is very pleasant....
Hi, wanted to know how we can migrate postgreys and snowflake using flyway in same active profile considering both have diffrent sql scripts that needs to excecuted independently.
Thanks,
Thank you so much for the video, I have a problem that needs help:
I have 2 branches: 1 branch "test" with database "test", 1 branch "production" with database "production".
So how to be able to synchronize database test and database production.
i don't grasp this idea, what changes the database schema are my entity models, spring applies all the necessary changes to the db schema by itself, so why wouldn't flyway integrate with spring and do this behind the scenes? i mean as it looks now i have to write all sql changes to a file!!! and to different db, spring orm already does that. i don't know, feels like more work for something which should be automatic.

Thank you!
Can we access table in other schema using flyway
good job thanks !
Thanks
flyway is a crap. no rollbacks and if your previous migration was changed, you should reinstall all migrations from the very beginning
Sounds like you have had some bad experiences with Flyway. It has matured quite a bit and is now one of the two de facto database migration tools utilized by the Spring Boot team.
When used with Spring Boot, so long as a Transaction Manager is configured in the ApplicationContext, Flyway wraps the execution of each unique Versioned migration in a transaction. Flyway will rollback the transaction if an error occurs during execution and commit the transaction if all of the statements succeed.
With regard to changing a previous Versioned migration after it is complete, this is something which teams must address as an Application Development procedure. I assume that you are referring to how a team of developers can work throughout a release on different features that require database changes. It is true that teams must work to find a creative solution to this matter and not use Flyway out-of-the-box per se. The process that has worked with the most success for me is to create a SQL file (not a Versioned Flyway migration file) that the team uses throughout the majority of the release cycle. Once we are ready to move our application to the User Acceptance or Pre-Production, or Staging environment, we know that 95-100% of our database changes are complete. We convert that SQL file to the Versioned Flyway database script for the release and test it when we deploy the application to that Pre-Production or Staging environment. The team uses the deployment to the Pre-Production environment as a dry run for the actual production deployment, so this serves as a great time to ensure that the Flyway migration executes properly against a database that still reflects the state of the prior release.
Thanks for watching! LS
LeanStacks thanks for sharing your experience :) but after working with flyway in 4-5 persons dev team, I think that liquibase is much better, because it provides for me features that helps just think about how to write my code better and don't think how to organize trivial things (we are in 2017!!!).
IMHO the flyway is a good solution for a pet project, but not for the enterprise
in any case, thanks for your gorgeous tutorials and very interesting feedbacks :)
