Subject Re: Looking for guidance on setting ZK session timeouts in AWS
Date Mon, 05 Dec 2016 16:32:59 GMT
Thomas,

I’m always running ZK separate from Kafka. Mind you, no multi-region, just
multi-AZ.
I have never had issues with default settings. It’s possible that once your
cluster gets bigger, you may have to increase the timeouts. Never had a
problem with cluster size of ~20 brokers.
Happy to hear from others though.

Best regards,

Thanks for the reply, Radek. So you're running with 6s then? I'm
surprised, I thought people were generally increasing this value when
running in EC2. Can I ask if you folks are running ZK on the same
instances as your Kafka brokers? We do, and yes we know it's somewhat
frowned upon.
