Flyway is an open-source database migration tool that facilitates Continuous Integration (CI) processes for any database platform. It uses a naming convention to refer to all Data Definition Language (DDL) and Data Manipulation Language (DML) changes made to the database, which are captured and versioned in a designated directory. Flyway supports multi-region deployments and can be used with YugabyteDB xCluster replication to handle data version control across multiple data centers. In an active-active deployment, both sides can perform reads and writes, while in an active-passive deployment, one cluster acts as the source and the other as the sink. By using dedicated Flyway instances for each region, database changes such as DMLs and DDLs can be easily propagated to other regions with minimal manual work on the replication setup. However, limitations exist, including the lack of automatic DDL replication and transactional replication, which are planned to be addressed in future enhancements.
