Subject [jira] [Reopened] (KAFKA-3927) kafka broker config docs issue
Date Tue, 05 Jul 2016 03:48:11 GMT

Shawn Guo reopened KAFKA-3927:
------------------------------

Thanks [~harsha_ch]

but I think they does have a default value in broker.
for example in my kafka_2.11-0.10.0.0/config/server.properties, I can find:
#log.flush.interval.messages=10000
#log.flush.interval.ms=1000

I also found default config in 0.8 broker configuration
https://kafka.apache.org/08/configuration.html
log.flush.interval.ms	3000
log.flush.scheduler.interval.ms	3000
log.flush.interval.messages	10000

I think above parameters are key performance parameters, it does not make sense to have "Long.MaxValue"
as default value.

> etc. obviously these default values are incorrect. how these doc get generated ? it looks
confusing.
