Hi All,
I was recently looking at how to make better use of parallelisation for
simple tasks in my compojure app, I had a construction similar to the
following:
(views/some-view (api/api-call-1) (api/api-call-2) (api/api-call-3))
It seemed that the easiest way to introduce some parallelism here would be
in the style of a let form:
(let [result-1 (api/api-call-1)
result-2 (api/api-call-2)
result-3 (api/api-call-3)]
(views/some-view result-1 result-2 result-3)
There doesn't appear to be anything in core that does, this - after a brief
discussion in the IRC channel, I received the following two suggestions:
https://gist.github.com/jcromartie/5459350 and
https://gist.github.com/guv/5459364
I ended up going with the approach from "guv", as I understood it better -
and I moved the let form inside the view function to cut down on the
repetition a bit.
Now, to my actual questions:
What are the differences between the pmap approach and the futures approach?
And would a construction like this be useful in core? If so, how does it
potentially get there?
Thanks
