Adam Holmberg commented on CASSANDRA-15958:
-------------------------------------------
Sorry I wasn't more precise on the third option. There, I was suggesting that
we stop trying to calculate the earliest possible prune, and just make it prune
periodically -- say every 10ms. Then there's no deadline to adjust forward or
backward and synchronize relative to new messages coming in -- it's just a
periodic task.
>Therefore, it seems a special case in the test. It should not harm in
>production.
It sound like in this paragraph you're agreeing with my option #1. If that is
the case (and we don't hear any opposition), when I get back to it I'll update
the test to be robust against this.
