Is there a way to cast a null-able attribute to not null-able attribute?
For example, this does not work:
AFL% cast(build(<x:int64>[i=0:9], i), <y:int64 not null>[i]); Error description: Error during schema inferring. Attribute 'y' flags doesn't match.
I guess this is because SciDB does not know what value
y should be if
x is null.
