Unclean leader election docs outdated
Hello Apache Kafka community,
Current unclean leader election docs state:
"In the future, we would like to make this configurable to better support
use cases where downtime is preferable to inconsistency. "
If I'm not mistaken, since 0.8.2, unclean leader election strategy (whether
to allow it or not) is already configurable via
unclean.leader.election.enable broker config property.
Kind regards,
Stevo Slavic.

Yes you are right. Could you file a JIRA to edit the documents?

That sentence is in both
https://svn.apache.org/repos/asf/kafka/site/083/design.html and
https://svn.apache.org/repos/asf/kafka/site/082/design.html near the end of
"Unclean leader election: What if they all die?" section. Next one,
"Availability and Durability Guarantees", mentions ability to disable
unclean leader election, so likely just this one reference needs to be
updated.
