Thanks for the responses gents. As a little background, the reason I'm considering node for this is because the datastore in question is Firebase - a real-time document store with a node sdk. It has a REST api too, so I don't *have* to use node, but it'd be nice to plug in to the real-time features.
I'm still getting the feeling that there is very little negative about doing this, and that mostly the negative feelings come from the fact that it's not the awesomest way of using node - rather than it actually being "bad". I'm not trying to compare awesome node to less awesome node, I'm trying to compare less awesome node to Java/Python/.net for a specific use-case. Prajwal, you said "use something lower level (thus faster) like JVM (Scala/Java) for this". Is that proven? Is Java faster at looping, and concatenating and adding numbers and such? The only benchmarks I see are web-related, so I just have no idea. Good point on the limited computation libraries tho - I don't think I need anything fancy but I should definitely make sure the libs I need are available in node before getting started. I've read some confusing stuff on memory, probably because things have changed quickly recently in V8 and node in that regard. It seems there shouldn't be a problem though because, as Ben mentioned, while the "JS heap is limited to slightly less than 2 GB, buffers and typed arrays live mostly outside the JS heap.". To be sure, what's an example of how I could run out of heap if I had, say, a 10GB array (outside of heap) that I'm processing? It terms of concrete "problems", the main (only) one I'm seeing is the added complexity of using the full resources of a machine without threads - implementing something like Persona as Prajawal mentioned (which looks very interesting thanks!) seems harder than threading. Pedro you say "Node is great for doing I/O and not much else", but this is exactly what I'm trying to get to the bottom of. I know this is the general drumbeat and I'm trying to find tangible reasons why.
