> Transaction pruning relies on inactive transaction bound (a bound that says
> at a given time there will be no transactions smaller than inactive
> transaction bound that can still be writing data). To determine the inactive
> transaction bound for a given time, TEPHRA-199 introduced transaction maximum
> lifetime.
> However there can be a delay between the transaction max lifetime being
> enforced and the write reaching HBase. Hence it would be good to use a buffer
> to pad the transaction max lifetime when pruning.
