A real-time stream system based on node.js

In contemporary, the value of data has increasingly been seen. We need to deal with different types of data in different ways. For some data types, their value will be reduced with the passage of time. As a result, when we receive the data, we need to deal with it as soon as possible instead of accumulation. For this point, Map-Reduce is not enough. This article will introduce a Real-Time stream computing system which is based on node.js and focus on real-time data processing, abbreviated as VRSS. In order to transmit data stream, we will use the channel mechanism of redis.
