Ariel Weisberg commented on CASSANDRA-19651:
--------------------------------------------
Thanks, I've also been triaging them, I don't think they are related to your
patch it's our CI environment, but when I did a baseline run of trunk there
were some that didn't seem to fail, but also a lot of noise.
I am going to try it on ASF CI for 5.0/5.1 and if that looks good I'll go ahead
and merge.
These don't appear yet since they are queued and haven't started

> idealCLWriteLatency metric reports the worst response time instead of the

> Actual result: responsesAndExpirations is a total number of replicas across
> all DCs which does not depend on the ideal CL, so the metric value for
> replicaPlan.keyspace().metric.idealCLWriteLatency is updated when we get the
> latest response/timeout for all replicas.
> Expected result: replicaPlan.keyspace().metric.idealCLWriteLatency is updated
> when we get enough responses from replicas according to the ideal CL.
