Free and stable is the winner. My plan is quite trivial - just put all the data in memory and use the cluster without changing the application code. Then, for persistence, I could just dump the data from nodes in a regular disk-access database. The only thing is, that since I demand in-memory storage, there is no possibility of full da...
I have a question that I cant seem to find an answer on. This is my first time using RabbitMQ in a "big" application and am wondering how the queues work in a cluster. I understand that the routing information (queues, exchanges, bindings) is on all nodes in the cluster, but the queue its self resides on the machine that it was created o...
Has anyone tried to apply a smoother to the evaluation metric before applying the L-method to determine the number of k-means clusters in a dataset? If so, did it improve the results? Or allow a lower number of k-means trials and hence much greater increase in speed? Which smoothing algorithm/method did you use? The "L-Method" is deta...
