-------------------------------------
Hi, dear Paulo.
I'd read such blog, I think now I'm clear with changes of Data.db in 3.x, I
tried to find something similar of changes on version 2.2 but I didn't find
anything, do you have any similar references or similar things, I'll try to see
if I can breakdown it, but it seems quite difficult in the sense that I'm not
familiar with Cassandra code base. Also before jumping to draw up the
framework, I'd like to know is our purpose downgrade an existing SSTable to
certain older version or add the possibility to write older version of SSTable?
Regards.

> As mentioned in other places such as CASSANDRA-8047 and in the wild,
> sometimes you need to go back. A downgrade sstables utility would be nice
> for a lot of reasons and I don't know that supporting going back to the
> previous major version format would be too much code since we already support
> reading the previous version.
