We do a 1 second cache locally within each client for a particular app. We do 10's of thousands of gets per second and this helped performance tremendously. So, depending on the specific of your app, memcache may help. --Brian ___ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
Basic Setup Question - Mac OS X
Hi everyone,
I'm new to Riak and am attempting to start up a 3-node cluster on one machine
(Mac OS X Mountain Lion) for Riak via
http://wiki.basho.com/Basic-Cluster-Setup.html
I downloaded and expanded the tarball for Riak 1.2 (no source to build, nice
and clean expansion). I then was able to get a single node running no problem,
with no special configuration. My Erlang version is R15B05, if you're curious,
but I don't think this has anything to do with it, as 1.2 is fully supportive
of this version.
I then recursively copied the directory riak-1.2.0 (the expanded tarball file)
three times to create top level directories riak1, riak2, and riak3. I then
proceeded to make the suggested changes from the link, changing the port
numbers to be unique for each instance. However, when I changed the vm.args
part (the name of the node from riak@127.0.0.1 to riak1@127.0.0.1 and the like)
from the link, I received the following error in the error.log file:
2012-08-09 01:21:04.288 [error] <0.161.0> gen_server riak_core_capability
terminated with reason: no function clause matching
orddict:fetch('riak1@127.0.0.1',
[{'riak@127.0.0.1',[{{riak_core,staged_joins},[true,false]},{{riak_core,vnode_routing},[proxy,legacy]},...]}])
line 72
When renaming the node in vm.args (the -name param) back to riak instead of
riak[new_number], everything works fine. However, as specified in the link, the
nodes need to have different names to cooperate with one another. As shown in
the error log, it seems like there is a name mismatch with something else when
I customize the name...? Is there some other config parameter that I haven't
seen that must be changed? I tried "raw_name" in app.config, but this didn't
make any difference. I appreciate any help I can get with this one. Thanks!

Re: Basic Setup Question - Mac OS X
Not only do they all need unique names, like you've done already, but they will
also need different ports. Look through the app.conf file and make all the
ports unique between your local nodes (http/https/pb/etc.).

Re: Basic Setup Question - Mac OS X
Michael,
If you delete the ring files from each release directory (rm -f data/ring/*)
and change the ports as Alexander mentioned then it should work for you. That
error message is not really very clear so that's something we should probably
work on improving, but since you already started the node as 'riak@127.0.0.1'
the quickest way to reset it is to delete the ring file. Also, there is a
devrel target in the Makefile that will generate 4 nodes for you with the ports
already setup. After running 'make devrel', just look in the dev directory and
you should have four release directories (dev1-dev4) ready to go. Hope that
helps.
