Issue with flyway clean command on EDB (EnterpriseDB)

Our EnterpriseDB is configured with multi-node with BDR is enabled. We use flyway clean command to wipe everything from existing schema and rebuild with latest flyway scripts (DDLs). Our EDB database is hosting multiple schemas and our flyway configuration is setup to target a specific application schema independently. With that, the flyway_schema_history table co-exists with other application specific tables within same schema.

Below is the error when we use flyway clean command:

I assume that having flyway_schema_history within application schema may be causing the issue as clean command is trying to drop the table which is required.

Please advice.

Thank you.

  • It seems the issue stems from the global lock conflict on flyway_schema_history during the flyway clean process. Try excluding this table or review locking configurations.

    The issue appears to originate from a global lock conflict on the flyway_schema_history table during the Flyway clean process. Consider excluding this specific table from the operation or thoroughly reviewing the database’s locking configurations to identify potential bottlenecks, ensuring a smoother and more efficient Flyway clean execution without conflicts.
