I am looking to setup Amazon EC/2 n开发者_运维问答odes on rails with Riak. I am looking to be able to sync the riak DBs and if the cluster gets a query, to be able to tell where the data lies and retrieve it quickly. In your opinion(s), is EC/2 fast enough between nodes to query a Riak DB, return the results, and get them back to the client in a timely manner? I am new to all of this, so please be kind :)
I'm not a Riak expert, but if you keep all of your EC2 instances in the same availability zone you should get more than adequate performance. AWS has a gigabit internal network and people have been able to get the full gigabit out of it; see this blog post for an example.
Marc-Andre,
Your best bet is to ask on the mailing list: http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
There's also lots of information on the wiki: http://wiki.basho.com/display/RIAK/Home
