Re: Can a message avoid loss occur in Kafka

For the config you provide, data loss should not happen (as long as you 
don't allow for unclean leader election, which is disabled by default).


But you might be subject to unavailability for some partitions if a 
broker fails.

Hello,
        Can a message avoid loss occur in Kafka. For example, my config is:


Producer
retries = Integer.MAX_VALUE
request.required.acks=-1


Broker
replication.factor >= 2
min.insync.replicas > 1
log.flush.interval.messages=1


Consumer
enable.auto.commit = false

  Can it avoid loss message occur in Kafka, if can not,  why? and does exist other MQ can do avoid?
