BigCouch load balancer

[YIXIAO SHEN <yi...@gmail.com>]

Hi all,

Has anyone used BigCouch to build CouchDB clusters? I'm following BigCouch
readme to do so, and I'm stuck here:

 'Because every node can handle requests equally, you may want to put a load
balancer in front of the cluster and set up a round-robin strategy for
distributing incoming requests across all of your cluster's nodes'

I don't have any idea of how to put a load balancer, could anyone kindly
tell me how to do so? Thanks,

yixiao

You could try HAProxy: http://haproxy.1wt.eu/

Hi Yixiao,

If you have a clustering software, just read the documentation (I am 
sure you will see round-robin there). If you don't have any clustering 
software, well, I don't know if BigCouch has any, but to create one it's 
not something one can attach to a post (at least I wouldn't because I 
have no information about your cluster). You can have an idea of what is 
round-robin from the wikipedia for example 
(http://en.wikipedia.org/wiki/Round-robin at computing and 
http://en.wikipedia.org/wiki/Round-robin_scheduling). Mainly it's about 
dividing your flux of incoming data into pieces and distributing them in 
a circular way to all the nodes (just to describe the strategy in simple 
words).

Cheers,
CGS

Hi!

I would use nginx. It's extremely simple and extremely fast.
http://wiki.nginx.org/LoadBalanceExample

Plus you'll get etag-based caching, serving static files and tons of magic tools :-)

If you're already using Rackspace services then I would recommend
their solutions. Especially if you're using their cloud/vm servers:
the load balancer option is pretty slick.
