----------------------------------------------------

Sorry for dropping the ball on this, the ticket doesn't show up in my normal Jira query (will figure out why later).  I've pushed an update to the branch addressing the review feedback; I think it's ready to commit with a quick +1 (CI is running [here|https://app.circleci.com/pipelines/github/belliottsmith/cassandra?branch=15375])

> This is odd:
> {{INFO [main] 2019-10-25 10:33:07,985 DatabaseDescriptor.java:803 - Back-pressure is disabled with strategy org.apache.cassandra.net.RateBasedBackPressure\{high_ratio=0.9, factor=5, flow=FAST}.}}
> When I saw that, I wasn't sure if back pressure was actually disabled, or if I was really using {{RateBasedBackPressure.}}
> This should change to output either:
> {{Back-pressure is disabled}}
> {{or}}
> {{Back-pressure is enabled with strategy org.apache.cassandra.net.RateBasedBackPressure\{high_ratio=0.9, factor=5, flow=FAST}.}}{{}}
