Riak Real Time Use Case Suitibility

2014-03-18 Thread James Hardy
Hi Everyone I'm new to Riak and was hoping someone might be able to give me some advice with how well suited Riak is to large data sets queried in real time. My potential use case is similar to the idea of storing the json for Twitter tweets in one bucket and then the json for the author of the t

Hi Massimiliano, As a first step I would recommend setting pb_backlog to 64 or 128 in your app.config How are you distributing the load from your python clients to the Riak cluster? Is every python client connecting directly to one Riak node or do you have a pool of Riak servers configured in eac

Hi Daniel, target_n_val can be changed at any time and will take effect at the first iteration of the claim algorithm [0] (which usually runs whenever you add/remove nodes from the cluster via the riak-admin command) On default settings, Riak is able to replicate data to distinct nodes in all clu

An explicit RiakError with 'timeout' as the string usually indicates that the server replied with that text in the response. You might need to check that the node(s) you are connected to aren't overloaded or having other issues. You can also make the timeout higher than the default 60sec by passing

Probably the easiest thing would be to wait until the new machine is ready to join, add it with a nodename distinct from that of the last one, and force-replace the new node for the old, dead one. On Tue, Mar 18, 2014 at 1:03 PM, Edgar Veiga wrote: > Hello all! > > I have a 6 machine cluster with
