 Returns estimation of uncompressed byte size of its arguments in memory.
 
-Use case: suppose you have a service that stores data for multiple clients in one table. Users will pay per data volume. So, you need to implement accounting of users data volume. The function will allow to calculate the data size on per-row basis.
