 - Doesn't work with [raw SQL queries](https://laravel.com/docs/7.x/database#running-queries). This would require an SQL parser to be implemented which is quite hard and very inefficient. As long as you are only using raw queries for reading data, it just won't get cached. Serious issues will only occur if you use raw queries for writing data (which you shouldn't be doing anyway).
 - Doesn't work with [multiple connections](https://laravel.com/docs/7.x/database#using-multiple-database-connections) if done like ``DB::connection('foo')``. Instead, specify the ``protected $connection = 'foo';`` property in the relevant models.
 - The cache must be truncated manually after migrations are executed.
-- Pessimistic locking (sharedLock, lockForUpdate) requires usage of [raw sql queries](https://github.com/spiritix/lada-cache/issues/49).
