- You can not tell riak where to place buckets. - You could set the N val on a bucket to one, and you should in the case of your 'big bucket'. Otherwise you will get N replicas on the same physical host. -Use linode. 512 > 256 = better.
But in reality , your use case doesnt mesh well with what riak is all about. distributed redundancy. I would use couchdb for your 'big bucket' of data. Couch uses a write only log (wol) filesystem with an incremental b-tree index for map reduce. This may work better for you. -Alexander On Aug 12, 2010, at 6:44 AM, Orlin Bozhinov wrote: > I can easily wait for Riak Search to do this > http://groups.google.com/group/mongodb-user/browse_thread/thread/c2563a8566591a30/b3d19f21675a899e > - instead of mongodb.
