I believe though that upgrading now is better than
later in the game. And if only with respect to not
needing any sstableupgrade runs.
It has the drawback of productization though as you write:
considerations like productization build changes and OpenShift
integration. There would be a data migration involved with OpenShift
since we already shipped Cassandra 2.x. When upgrading across major
versions, you are supposed to run the sstableupgrade utility on each
table. We would need to do this for OpenShift. Whether or not we
choose to upgrade now, we will need to deal with this migration step
in OpenShift at some point.
Yes. What runtimes are expected here? If they are typically in
some minute ranges, then they could be more or less be done
during a normal openshift version upgrade I guess.
