This practical question is based on COVID 19 Contact Tracing using Map Reduce Algorithm. During the onset of the COVID pandemic, it was a challenging task to perform Contact Tracing because of many reasons. To create a preparedness plan, your services as a Data Science expert have been retained to create a Data Processing Model that will help to process the Contact Tracing details faster. You have been supported by the authorities who have urged people having been in contact with suspected cases to register themselves in a dedicated portal which is available 24/7. The following operational assumptions are to be made: - We reported a pair (or more) as suspect if they were at the same space at the same time for a period of more than 3 minutes; - Number of days of observations for the whole program is continuous; - Every time a new case is discovered, they are sent to the monitoring department of health department for treatment and follow up. Design a Map Reduce framework that will identify cases based on the information collected. You can design the data capture portal for the requirements of the Map Reduce Algorithm. Your final answer should be in the form of a concise technical report which includes: Data design (collect) and granularity Example of dummy data Map Reduce Model Map Reduce Processing Execution and detection of Map Reduce Cases Advantages and challenges of your model.create a
