Hi everyone, I'm fairly new to writing services in Clojure, but I recently encountered a situation where I wasn't sure whether to use map/pmap. The mapping function was approaching the point where pmap might make more sense, but I was often editing that mapping function. Moreover, my production environment is, of course, a bit different than development. So I wasn't sure which would be optimal.
Would anyone else find it useful to have a "generic map" that, after recording a few execution times, decides whether to use the parallel or single-threaded version of map? I wrote up a v1 here: https://gist.github.com/karansag/bab7ea1a4613dfd929ea. The code is actually applicable to any parallel-izable sequence operation if you add the operation's parallel dual to "parindex." Excuse all the do/println statements. Anyway, if people think this would be useful I can spin it off into a (micro)library. The current API requires you to add a var that creates a special "dynamic map" -- e.g., (def dynamic-map (dynamicp map)), but I could change that or make it easier to use on the fly. Maybe something like (dynamic-select (map ...)), where dynamic-select is a macro that adds that var to your namespace and uses it in place of map.
