Github user poornachandra commented on the issue:

    Thanks for the review @anew. I've addressed the comments, please take another look.
    > Regarding correctness, my major concern is that the (min(max invalid), min(inProgress)-1)
is not a safe bound for transaction that are guaranteed not to write any more.
    I have filed TEPHRA-199 to address this, I'll make the changes in the next PR.
    Do you have a suggestion for a better name for `pruneUpperBoundTime`? Basically this is
an upper bound for transactions that are not active (i.e, can be still used for writing).

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
