Data Velocity

Big Data is not only storing large amount of data and processing it in economical way to pull some oil or value out of it.

We have to handle the speed of Data Generation & Data Delivery also. 

Lets observe some examples -

Sensor Data     [Thermometer sensing temperature and collecting data continuously]
CCTV Cameras    [Capturing Images continuously]
FB Posts        [Adds 500+ TB per day]
Tweeter data    [98,000+ Tweets per 60 seconds]
YouTube Videos  [60 Hours of videos uploaded per minute]
Mobile Towers   [Collects few GB's of data every hour]
...etc
(Approximate figures collected from some websites)


there are many more real time examples which are generating data at very high speed.
Big data technologies have to handle this challenge which we call "Data Velocity".
