Subject Composite Column Expiration Behavior
Date Wed, 18 Jul 2012 15:44:27 GMT
Hi there,

I am trying to understand the expiration behavior of composite columns.
Assume I have two entries both have the same parent column name but each
one has a different ttl. Would expiration be applied at the parent column
level (taking into account ttls set per column under the parent and
expiring all of the child columns when the most recent ttl is met) or is
each each child entry expired independently?

Would this be correct?


t+5: Nothing gets expired (because A:C's expiration has not yet been
t+10: Both A:B and A:C are expired
