Preferred load balancer option for PQS

Hi,

I am trying to add a load balancer for query server and after reading 
documentation, I am a little confused on which option to pick. go with a 
traditional load balancer ( thinking of ELB) or the inbuilt zookeeper 
based load balancer. Is there an advantage of using ELB over the 
zookeeper based one ? ( I am not using Kerberos, so thats not an issue).


Thanks,
Jins George

Hi Jins,

Check out 
https://community.hortonworks.com/articles/9377/deploying-the-phoenix-query-server-in-production-e.html 
which should cover a bit of this (specifically, via HAProxy).

I wrote this prior to the ZK-based discovery and client-driven load 
balancer which has showed up recently. As for what PQS needs from a load 
balancer, the only requirement is for sticky sessions. With that, and 
relatively stable backend servers, a dumb HTTP load balancer should work 
just fine.
