Jun Rao commented on KAFKA-1530:
--------------------------------
We do have an option "unclean.leader.election.enable" to prevent unclean leader
election. So, if you care more about durability than availability, you can set
this option to false. Then, the new leader will only be elected from isr. The
unavailability window of a partition could be longer though since we have to
wait until at least one broker in isr is back online.

> Hi,
>
> Could I ask you a question about the Kafka update procedure?
> Is there a way to update software, which doesn't require service interruption
> or lead to data losses?
> We can't stop message brokering during the update as we have a strict SLA.
>
> Best regards
