All database operations are transactional. You can disable this functionality
in your Aurora_ classes by setting the transactional property to false.
For example:
class Aurora_Event extends Interface_Aurora_Database, ...
{
...
public $transactional = FALSE;
...
}
Aurora adds Profiler Marks for you to benchmark your application, detailed for each method of the Core API, all under the single "aurora" category.
You JUST need to enable Kohana profiling (which is enabled by default)
You may read the official manual about profiling here.
