You could make a column family for each period of time and then drop the column
family when you want to destroy it. Before you drop it you could use the
sstabletojson converter and write the json files out to tape.
Might make your life difficult however if you need an input split for map
If I'm understanding you correctly, you can write TTL's on each insert.
18 months would be roughly 540 days which would be 46656000 seconds. I've not
tried that number, but I use smaller TTL's all the time and they work fine.
Once they are expired they get tombstones and are no longer

My understanding was that TTLs only apply to columns and not on a per row
basis. This means that for each column insert you would need to set that TTL.
Does this mean that the amount of data space used in such a case would
index for that, I would assume.

Just make month time stamp a part of row key. Then once a month select old
data, move it and delete.
