> 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.
