----------------------------------------------------------------

I went through the feature 3974, I don't quite understand what I should do to 
add the ttl property. 
is the change by updating the cql to "UPDATE system.transaction USING TTL 
DEFAULT_VALUE" in class SystemKeyspace a correct fix?

> we should save the compaction merge stats from CASSANDRA-4894 in the system
