Liquibase Documentation
What is Liquibase?
Liquibase is an open-source database schema change management solution which enables you to manage revisions of your database changes easily. Liquibase makes it easy for anyone involved in the application release process to:
- Eliminate errors and delays when releasing databases.
- Deploy and roll back changes for specific versions without needing to know what has already been deployed.
- Deploy database and application changes together so they always stay in sync.
Frequently Asked Questions

Yes. Since each change is independent, database changes that had been made in a different branch, then merged in will be run the next time Liquibase is run. You may run into a problem with the order that the statements are ran, but any issues you have can be easily solved by re-ordering the changelog files.

Liquibase Open Source is released under the Apache License, version 2.0. Liquibase Pro is released under a commercial license. The main Liquibase jar file also contains commercially licensed Liquibase Pro code that is only active when a license key is provided.

Liquibase uses a distributed locking system to only allow one process to update the database at a time. The other processes will simply wait until the lock has been released.
