Description
Instead of relying on hadoop to do a mapreduce, it would be really useful to call c++ or java or python or ... libraries from inside mongo mapreduce, and a way to do this would be to allow to do get or post request to a localhost server
If I am not clear, imagine the following :
you have :
- a mongodb containing lots of pictures
- an awesome library in c++ that tells you if you are on the picture or not
you want to do :
- make a c++ server that runs on localhost:12345 and that takes a picture as an argument and returns true or false
- mapreduce over your library (or foreach) and call the server with your data
I was originally thinking of an EASY way to call external (c++/...) libraries from mongo without going through hadoop, so maybe you have other ideas ! As long as it can ease a lot of pain for users I am fine
Thanks !
