I am trying to design my schema using composite column. One thing I am a bit confused is how to define validation_class for the composite column, or is there a way to define it?
for the composite column, I might insert different value based on the column name, for example
I will insert date for column "created":
user['7:1:100:created'] = 1351728000;
and insert String for description
set user['7:1:100:desc'] = my
I don't see a way to define validation_class for composite column. Am I right?
