load balancer is just an option. Up to you to decide the necessity, but I
really would offload work to other idle system. Anyway since the load is small,
it is not a big issue. Frankly speaking, if using round-robin, the code logic
change seems to be really small.
For proxy, the cps should be high enough normally. Even if the cps is low, why
not use load-balance (e.g. round-robin) in hawq code directly since adding an
additional proxy (I assume you mean reverse proxy kinda thing) will introduce
unncessary latency, besides, the "proxy" will need HA also.

> Once Ranger is configured, HAWQ will rely on RPS to connect to Ranger. A
> single point RPS may influence the robustness of HAWQ.
> Thus We need to investigate and design out the way to implement RPS High
