Ionut, To consistently execute a transaction you have to acquire locks on all the participating keys and have a coordinator that knows whether all the locks are successfully acquired or not. If if it's possible to implement semantics you're describing, it will not come for free and will produce significant overhead. I'm pretty sure that this overhead will be much bigger than executing an SQL query to fetch required keys.
