bq. BUT Michael Semb Wever made it possible to run all of them in Jenkins where
the failures are still a lot.
Many of those ~700 failures, currently, are the same thing {{'ProtocolError
returned from server while using explicitly set client protocol_version 4'}}.

Diff testing workloads has proven to be one of the most powerful ways to confirm mixed version clusters are behaving, and we can reasonably expect a post CASSANDRA-8099 cluster to 4.0 to have significantly less risk and exposure to defects than the straddle as they don't rely on LegacyLayout. I don't see much of a path other than having a corpus of real user schemas we can run through cassandra-diff w/a generative workload and forward + reverse iteration to confirm correctness; we're not there yet, and while we should have the framework to accept that in the relatively near future, I think blocking a 4.0 release on us building up that collection of anonymized schemas is a pretty big set of unknowns. So the current relatively inadequate technical coverage we have (afaik) is in upgrade_tests in the dtest repo ([link|[https://github.com/apache/cassandra-dtest/tree/master/upgrade_tests]]). I frame as inadequate because they didn't catch a bunch of the things that had sharp edges in the StorageEngine rewrite so clearly our mixed version cluster testing wasn't as robust as we'd hoped. Looks like we have a candidate to build from in UpgradeTestBase.java we could start to specifically flesh out if we had a PoV on things to test. I'd advocate for us building more there than investing further in dtests. So: long winded way to say "Hm. Not sure what we should do here." [~jjirsa] - got any ideas in terms of a straw man proposal of things we should test on mixed version clusters from a unit perspective, or is integration the way to go here? > 4.0 quality testing: Cluster Upgrade > > > Key: CASSANDRA-15588 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15588 > Project: Cassandra > Issue Type: Task > Components: Test/dtest/java, Test/dtest/python >Reporter: Josh McKenzie >Priority: Normal > Fix For: 4.0-beta, 4.0-triage > > > We've historically had numerous bugs concerning upgrading clusters from one > version to the other.
