--------------------------------------------------------------------
Thanks everyone for the comments. Phoenix is a row-based system, it is better
to expire the whole row rather than a portion of a row.
The parser takes different parameters for CREATE TABLE and ALTER TABLE.
CREATE TABLE takes (p=fam_properties)
ALTER TABLE takes (SET (p=properties))
CREATE table can specify TTL for different column families. ALTER table sets
TTL for the whole row.

flexibility, provide a column family TTL should be fine as well.
