My preference is for each client application node to connect to an instance of haproxy on the localhost, that way cluster changes only requires updating and reloading the haproxy config--which is cleaner and safer for production services.
An example haxproxy config can be found on the Riak docs: http://docs.basho.com/riak/latest/ops/advanced/configs/load-balancing-proxy/#HAProxy On Fri, Aug 15, 2014 at 11:32 AM, Daniel Simms <daniel.si...@gmail.com> wrote: > < 2.0 the java cluster client was actively unhelpful (in that it didn't > track node health, so if one node was down, the client would regularly try > it still, IIRC), and a client-local haproxy (or such) is the way to go. > > >= 2.0 the java cluster client looks like it's smarter about tracking node > health (but I'm not using it in anger and therefore don't know if it's > otherwise suitable and would be curious if anyone is happily using it > without haproxy) > > > On Fri, Aug 15, 2014 at 6:18 AM, Paul Barry <paul.ba...@temetra.com> > wrote: > >> We’ve been using Riak with Java client for more than two years in >> production, and best solution is ha-proxy. >> Your Java client connects to one ha-proxy, configured for round-robin to >> all the nodes.
