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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
