riak search sort question?

Hi, I have used this one in search request( *sort=FIELDNAME*-- Sort on the specified field name. Default is "none", which causes the results to be sorted in descending order by score.) Assume the fieldname is a change_date. I got the result and sorted by change_date ASC. Howto DESC the resultS

blocking get call?

Does riak have a "blocking get" call? I'm thinking of something that works like this... if a GET call is made for an object that doesn't exist, the call blocks until the object is created. ___ riak-users mailing list riak-users@lists.basho.com http://lis

Dead connections with load balancer

Re: Testing On A Single Node

Hi Joe, A standalone node should behave similarly to a clustered node in terms of data persistence. Actually, I use single-node Riak setups (inside a VM) a lot for testing. The only differences are ring_size=8 and n_val=1, for performance reasons. So, it must be your Riak or VM configuration. Als

Re: Continuous HTTP POSTs to Riak

Hi Qiang, Since you are running with allow_mult=false, make sure the clocks of your Riak nodes are synchronized. If they are out of sync, newer values may get overridden by older ones on read, depending on the node a request hits first. Of course this won't cover 100% of cases because a perfect cl

FWIW, on ubuntu you can drop a file in /etc/security/limits.d/ called 'riak.conf' with the appropriate stanzas you would normally include in limits.conf and it will get read. If you use chef or puppet, this is much easier than trying to have multiple resources attempt to manage limits.conf togethe

Re: Node cannot join

It might be worth looking at the Chef cookbook for how it does it. As I see it on a fresh install with no data, there's probably not much major risk in concurrent joins. On an existing install, however, I'd think you would want to go serially. We stand up all of our riak clusters from scratch usin

As an opposing viewpoint, I'd argue that it's NOT the requirement of Riak to go automatically changing things outside of its domain.
