The largest known riak cluster != the largest possible riak cluster. ;-) The inter node communication of the cluster depends on the data set and usage pattern, doesn't it? Or is there some constant overhead that tops out at a few hundred nodes? I should point out that we'll have big data, but not a huge number of keys.
The number of vnodes in the cluster should be equal to the ring_creation_size under normal circumstances, shouldn't it? So when I have a one node cluster, that node is running ring_creation_size vnodes... File descriptors probably isn't a problem -- these machines won't be doing anything else, and the limits are set to 65536. Thinking about the internode communication you mentioned, that's probably where the resource hog is.. socket buffers, etc. Anyway, I'd also love to hear more from basho. :) On Wednesday, April 13, 2011 at 12:33 PM, sicul...@gmail.com wrote: > Ill just chime in and say that this is not practical for a few reasons.
