Chris Burroughs commented on KAFKA-164:
---------------------------------------
There are good things to be said about having the default configuration be the
"overly paranoid do not loose your data" one, even though once they think about
what that means no one actually wants that. I'd stick with round numbers and a
note elaborating on the trade-offs.
> Config should default to a higher-throughput configuration for
> log.flush.interval

> Currently we default the flush interval to log.flush.interval=1. This is very
> slow as it immediately flushes each message. I recommend we change this to
> 20000 and drop the time-based flush to 1 second. This should be a good
> default trade-off between latency and throughput.
