Riak behind a Load Balancer

There's a reference to an article on Basho's site, written by Amazon, about Dynamo: 

http://features.basho.com/entries/20535121-weighted-nodes 

Section 6.4 explains why they do not use load balancers. 

The rest of the article is good reading, too.

Matt, 
Haproxy is my load balancer of choice. You can always run multiple copies of haproxy and use some type of dynamic dns with it. 


We do this in many cases. Haproxy scales well. I've seen a single node sustain multiple gigabits per second with almost no sweat. 




Thanks.

Dear list, 


Does anyone have an opinion on the concept of putting a Riak cluster behind a load balancer? 


We wish to be able to automatically add/remove nodes from the cluster, so adding an extra layer at the front is desirable. We should also benefit for incoming requests behind shared across all nodes. 


Can anyone see any drawbacks / problems with doing this? 


Thanks 
Matt
