Datastream API (with its HTTP interface) is a library for collecting and visualizing time-series data. It is used in nodewatcher to store and visualize measurements from nodes in a mesh network. Such visualizations through time allow better insight into network's status and operation for both experienced and novice users. Current implementation provides a RESTful API for fetching data to the client (browser) side for visualization. The issue is that for real-time visualization of such RESTful API requires from the client side to constantly poll the API endpoint for new data. A better model would be to use a push based API to get data from the server as new data is available (probably as a publish/subscribe pattern).

The aim of the GSoC project is to design and implement a HTTP push based API for Datastream and integrate support for it into current client-side visualization code. Visualization should be able to read and update in real-time as new data arrives. Student should have experience or be willing to learn Python and Javascript and HTTP push based technologies, probably Django/node.js/Meteor/Tornado or some other suitable stack. (Current RESTful API is implemented in Django.) Datastore for Datastream data is MongoDB.
