Jay Kreps commented on KAFKA-1028:
----------------------------------
There is some information on writing system tests for kafka here:
https://cwiki.apache.org/confluence/display/KAFKA/Kafka+System+Tests
I don't know that jepsen itself is actually needed. I think what Jepsen does to
perturb the network is just use iptables and tc (traffic control).
If you can read lisp you can see it here:
https://github.com/aphyr/jepsen/blob/master/src/jepsen/control/net.clj
> per topic configuration of preference for consistency over availability

> As discussed with Neha on the ML.
> It should be possible to configure a topic to disallow unclean leader
> election, thus preventing the situation where committed messages can be
> discarded once a failed leader comes back online in a situation where it was
> the only ISR.
> This would open kafka to additional usecases where the possibility of
> committted messages being discarded is unacceptable.
