Rajiv, By default, the quota is unlimited until you decide to configure them explicitly. And yes, we did get rid of "replica.lag.max.messages", so that configuration will no longer apply. Aditya On Tue, Dec 1, 2015 at 10:24 AM, Todd Snyder wrote: > The quota page is here: > http://kafka.apache

RE: Sporadic Shrinking/Expanding ISR Blips

2015-06-29 Thread Aditya Auradkar
In addition to "replica.lag.time.max.ms", please also revisit "replica.lag.max.messages". Simply increasing the lag time won't prevent ISR blips. Since the lag is calculated based on number of messages, a single large commit on the leader can throw a follower out of ISR. Aditya ___

Is that necessarily the case? On a cluster hosting partitions, assuming the leaders are evenly distributed, every node should receive a roughly equal share of the traffic. It does help a lot when the consumer throughput of a single partition exceeds the capacity of a single leader but at that po
