CatalogValidationFailureHandler
@DefaultImplementation(value = LoggingCatalogValidationFailureHandler::class)
At the start of the READ operation, the connector configuration, the configured catalog and the input states are validated against each other. For instance, a catalog may have grown stale after a schema change in the source database. All validation failures are passed to this interface. The production implementation will log a message while the test implementation collects them in a buffer for later inspection.
