How fast are EC/2 nodes between each other?

Hi,

I am looking to setup Amazon EC/2 nodes 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 :)

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

Marc edited the question, he didn't ask it.

Thank you Sean! (This is Tyler from raleigh ruby). I am new to all of this and will mail the team with a similar question.

Actually, I have just gotten riak setup and am beginning to play with some of its features. I am going to have to get my rails app setup to connect with EC2 so that I can deploy another instance on the fly. Of course, I am still learning how all of that really "works", so off I go to read more!

+1 A:

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.

Thank you Gareth! I have continued my search and am thinking about putting the riak datastore on an external EBS volume for better performace and so that if an instance is deleted, I don't lose the data on that ec2-instance. I suppose that would mean I start with one instance attached to multiple EBS disks, and then add instances and spread out the disks among them as I need performance. Am I thinking about this the right way?

tesmar 2010-03-29 19:25:55

@tesmar, your approach sounds good - note that you can make an EBS volume pretty much as big as you like (although you pay per GB), so you may not need multiple volumes - again - I don't konw enough about Riak to answer that properly.
