MariaDB

Connect a MariaDB database to Lakehousecat using a connection URI.

Connection Fields

Field	Required	Description
Connection URI	Yes	Full connection string including credentials, host, port, and database name. Example: mariadb://user:password@host:3306/mydb
Use SSH	No	Enable if the database is behind an SSH bastion host. When enabled, SSH settings fields appear. See SSH Tunneling.

Prerequisites

• Admin or Builder role in Lakehousecat
• A MariaDB user with SELECT access to the schemas and tables you want to expose
• Network connectivity from the Lakehousecat backend to the database (direct or via SSH)

Notes

• MariaDB is MySQL-compatible — the connection uses the MySQL protocol internally.
• Use a read-only database user to follow the principle of least privilege.
• Incremental Load is supported; use a timestamp column (e.g., updated_at) as the merge key.

Next Steps

After creating the datasource, go to the Operations tab to trigger semantic extraction.
