Jeffrey Zhong commented on PHOENIX-1240:
----------------------------------------
{quote}
it's fine to have a TTL on a column family, but not if it's the column family
that contains the empty key value
{quote}
How we deal with the case that required(not null) columns in column families
with shorter TTL values? Or alter table to add a not-nullable column to a short
TTL column family.
> Add TTL to SYSTEM.TRACING_STATS table
