Overview

v4 MySQL adapter using database-per-tenant isolation (mysql2 driver).

Resolves tenant-specific connection configs by setting the ‘database` key to the environmentified tenant name. Lifecycle operations (create/drop) execute DDL against the default connection.

Instance Method Details

#failsafe_error_classes ⇒ Object

The database-per-tenant missing-tenant error: connecting to a dropped database raises ActiveRecord::NoDatabaseError (MySQL error 1049) — an unambiguous signal. It surfaces raw at query time, or wrapped in ApartmentError when ConnectionHandling resolves the pool (the dev-mode pending-migration check), so both are listed; #container_error? gates on the unwrapped NoDatabaseError. Inherited by TrilogyAdapter.
