Aleksey Yeschenko commented on CASSANDRA-5576:
----------------------------------------------

Mentioned it to highlight how important getting the schema of system tables 
right the first time is. Changing it is hard. Removing columns - almost 
impossible. If we can have one less from the start, I'd much rather prefer it. 
And we *will* add trigger parametrization in the future - so why not add 
trigger_options map<text,text> right now and keep the class there, instead of 
having a separate trigger_class column? Not having to touch schema_triggers 
schema in the future = win.
