node.js - NodeJS to poll data from N sources every X seconds -

-

is nodejs choice poll data n third party sources on rest interface.

i need (almost) parallelize can support real time updates.

question - nodejs choice this?

another caveats are:

  1. if response large each polling , rapid (perhaps in 100s of megas) must try use multiple node processes.
  2. server response each polling should less interval time of polling cycle else may hit condition process may become unresponsive , fail.

you may choose use reactive programming scenario. try rx.js. in handling process in controlled manner.
