1 decrypting spark streaming operating mechanism Last lesson we talked about the technology industry's Dragon Quest. This is like Feng Shui in the past, each area has its own dragon vein, Spark is where the dragon vein, its dragon Cave or the key point is sparkstreaming. This is one of the conclusions we know very clearly in the last lesson. And in the last lesson, we adopted the way of dimensionality reduction. The so-called dimension of the way, ref

Now the continuous development and progress of network technology, the arrival of big data, so that network bandwidth increases rapidly. Because of the progress of the Times, the network and streaming media technology to show the opportunity and display, and also for the campus video Live network transmission audio and video data has laid a good foundation.
