Dear all, I really love programming in Clojure, and have done so for the past couple of months, building my company's software recommendation engine in Clojure (not in production yet), which I originally wrote in Ruby. However I have run into the following a memory problem, which actually was pointed out by Christophe Grand in a response on stackoverflow (http://stackoverflow.com/questions/749911/how-can-i-leak-memory-in- clojure).
In my case I want to calculate (usage) correlations between items, and pick for each item its most similar items. For example, If I compare one item with 1.000.000 others, and calculate their similarities, then next I sort the collection, and pick only the top (say 10) Artificial code example: (take 10 (sort (for [x (range 1000000)] (rand))))) Now the problem is the memory usage, as it does not merely uses memory space for 10 items, but it keeps a reference to the entire sequence. If I leave out the sort its all ok, and done lazily. Does anyone know how to sort and avoid large memory consumptions? Thanks in advance.
