Anoop Sam John commented on HBASE-11764:
----------------------------------------
bq. Cell tags cannot extend the lifetime of a cell beyond the family setting
I am +1 for that. CF can be set with max possible TTL and when there is a need
to store some cells with more TTL value than this, one can always alter the CF
setting.(Will get applied to new files created from then on (?) )
If we have to handle the case of per cell TTL > cf TTL, we have to track the
per cell TTLs and write down this meta in HFile so that file level early out
optimizations can be continued. Given the current way being simple, that would
be good enough.
