Java input streams are blocking, rather than asynchronous, so yes it would use a thread per stream.
In theory an asynchronous solution would be more efficient, and there are adapters, like http-kit, that support this optimisation. However, in practice, Java can handle many threads in a single process, so it's unlikely you'll run into difficulties until you have to support 1000s of concurrent downloads. It's often a good idea to avoid premature optimisations, particularly if you lack concrete benchmarks. It also depends a lot on how you're generating the downloads. If you're generating the files dynamically, you may find that your bottleneck is CPU-bound, rather than I/O-bound; in which case, there would be little benefit to going async. If you're just serving static files, then it might be useful hosting your files on a service like S3, and redirecting your users instead. - James On 23 April 2014 04:03, Andrew Chambers <andrewchambe...@gmail.com> wrote: > When you set the body of a ring response to a java input stream and return > it, is this still a thread per stream? or does it use some sort of java > event loop for efficiency? > I'm worried that a traffic download/upload server in ring wouldn't handle > many concurrent large file uploads and downloads as efficiently as > something like google go or nodejs would. > I would like to use ring because I want Datomic to manage the access > permissions. > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > --- > You received this message because you are subscribed to the Google Groups > "Clojure" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to clojure+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
