[Flask] REST based File Sharing server Implementation in Flask ub at artfacts.net

[G.S.Vijay Raajaa]

The number of non-block servings will correspond to the max number of
workers in that case? Hypothetically if one user uploads multiple
files that keeps all the workers busy, I am blocked when rest of the
users online trying to upload files. Any thoughts to delegate it
asynchronously?

*well, there will be workers. if you deploy your app in uwsgi or gunicorn,
you set the number of workers in you config. these will then handle
requests (more or less) indepently.
pymongo will have a connection pool to also handle multiple connections. [2]

*i guess here's the bad news. it might be slower than writing directly to
the file system, but it might be better when you have app and storage
separated and need to write your files over the network. but you need to
consult benchmarks to be sure.

*i think here's the upside. also seems, mongodb can help you to store and
