Description

In the current implementation we are propagating the selected array (using filterContext) to the appropriate subtypes to allow row-level skipping.

This works for basic types such as Decimals and complex ones like inner structs there is 1-1 mapping in the rows, however it more complex for nested types such as Lists or Maps where the number of inner rows is different and thus needs special handling.
