---------------------------------------

             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.
