Re: Looking for guidance on setting ZK session timeouts in AWS
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, Radek Gruchalski ra...@gruchalski.com On December 5, 2016 at 5:27:05 PM, Thomas Becker (tobec...@tivo.com) wrote: 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. -Tommy On Mon, 2016-12-05 at 11:00 -0500, Radek Gruchalski wrote: > Hi Thomas, > > Defaults are good for sure.

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?

Hi Thomas, Defaults are good for sure.
