Usage of Big Data techniques
- Take the example of the traffic lights problem.
- There are more than 300,000 traffic lights in the US as of 2018.
- Let us assume that we placed a device on each of them to collect metrics and send it to a central metrics collection system.
- If each of the IOT devices sends 10 events per minute, we have 300000x10x60x24 = 432x10^7 events per day.
- How would you go about processing that and telling me how many of the signals were “green” at 10:45 am on a particular day?
- Consider the next example on Unified Payments Interface (UPI) transactions:
- We had about 1.15 billion UPI transactions in the month of October, 2019 in India.
- If we try to extrapolate this data to about a year and try to find out some common payments that were happening through a particular UPI ID, how do you suggest we go about that?
