---------------------------------------
Summary: Raft should not prevent truncation below high watermark
Key: KAFKA-12460
URL: https://issues.apache.org/jira/browse/KAFKA-12460
Project: Kafka
Issue Type: Sub-task
Reporter: Jason Gustafson
Assignee: Jason Gustafson
Eventually we will have to come up with some approach to recover from committed
data loss in the raft quorum (something akin to unclean leader election for
normal partitions). For now, we would rather be stricter and fail fast rather
than allowing committed data to be silently lost. The long term thought I have
in mind is to give users an --unsafe flag or something like that which can be
passed at startup in order to knowingly turn of the stricter validation in
order to let the quorum recover from a disaster scenario. This needs some more
thought though.
