add-database-driver

To add a new database driver, you scaffold the driver skeleton, implement the driver interface, and register it in the central registry. This creates a reusable pattern to add support for a new database type to Mako's multi-database execution system.

Implementing schema introspection and query execution requires the getMetadata, getTreeRoot, getChildren, and executeQuery methods. These enforce schema discovery and query execution, with executeQuery requiring AbortSignal support for cancellation.

Query cancellation works by passing an AbortSignal to the required executeQuery method. This AbortSignal support is enforced during driver scaffolding, and optional cancellation steps can be validated through the provided testing procedures.

To verify a newly scaffolded database driver, you follow the provided test steps to validate tree navigation, query execution, and cancellation support. This ensures the driver correctly implements schema discovery and query handling before integration.

Yes, you need to register the scaffolded database driver in the central driver registry. This registration step is a core part of the scaffolding process and enables quick integration and consistent query support for the new database type.
