Cassandra Migration

cassandra-migration is a simple and lightweight Apache Cassandra database schema migration tool.

It is a Kotlin fork of Contrast Security's Cassandra Migration project, which has been manually re-based to closely follow Axel Fontaine / BoxFuse Flyway project.

It is designed to work similar to Flyway, supporting plain CQL and Java-based migrations. Both CQL execution and Java migration interface uses DataStax's Cassandra Java driver.

Limitations

The tool does not roll back the database upon migration failure. You're expected to manually restore from backup.

Resources

Refer to the Project Wiki for the full documentation.

    • For new features, use feature/ prefix followed by the feature name, e.g. feature/feature_name
    • For bug fixes, use bug/ prefix followed by the short description, e.g. bug/fix_this_bug
