Hi all,
we have a cluster of 0.9.0.0 with 3 nodes, we have a topic with 3
replicas, and send it with ack -1, our sending latency is avg 7ms. I prepare to
optimize performance of cluster through adjusting some params.
we find our brokers has set config item as below,
log.flush.interval.messages=10000
and other relevant parameter is default, and I find the default value of
log.flush.interval.messages is LONG.MAX_VALUE, because of setting this config
will flush intiative that may affect performace . I wonder can I cancel this
config item’s setting, and use default value.
I think use default value may have two drawback as below.
1.recovery checkpoint can not be updated，so when load
segments，it will scan from begin to end.
2.it may lose data when leader partition’s broker’s vm is
restart，but I think 3 replicas can remedy this drawback if the network between
them is good.
any suggestions? thank you
