IMO, we should leverage existing specialized frameworks, like Jepsen
. The Nemesis component supports *much* failure modes. The example
test scenarios and associated publications cover many existing database
and messaging solutions. Although community could contribute for the
latter as well, like adding RabbitMQ RPC example test cases to the repo,
or for a fork at least, I think the Nemesis "disruptor" would benefit us
