Subject: Retrieving old data version for a given row
I'm trying to retrieve old data version for some row but it seems not
be possible. I'm a beginner  with Cassandra and the unique aproach I
know is looking to the SSTable in the storage folder, but if I insert
some column and right after insert another value to the same row,
after flushing, I only get the last value.
Is there any way to get the old data version? Obviously, before compaction.
