[jira] [Commented] (CASSANDRA-15375) Remove BackPressureStrategy
[ https://issues.apache.org/jira/browse/CASSANDRA-15375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17105672#comment-17105672 ]
Jordan West commented on CASSANDRA-15375:
-----------------------------------------
Sorry to come in late on this when there is already a patch but shouldn't we deprecate {{RateBasedBackPressure}} before removing it? I understand folks here haven't seen it in the wild but that doesn't mean someone isn't using it.

> {{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}}
