Benedict Elliott Smith commented on CASSANDRA-16935:
----------------------------------------------------

This patch has a [lot of CI runs|https://app.circleci.com/pipelines/github/belliottsmith/cassandra?branch=16935-trunk] showing the same flaky failures as CASSANDRA-16934 and trunk, except for {{testConsistencyV22ToV3X}} which has occurred only once in a sequence of runs and appears to be caused by an entirely unrelated assertion error in {{Keyspaces}} related to jdtest shutdown.

> This patch introduces a config property for specifying the desired Paxos implementation and semantics. Initially, this will support only v1_norrl and v2, with “norrl” meaning “no read/read linearizability” i.e. supporting those use cases that need to restore prior performance, but only for read/read interactions.
