PySpark and AWS: Master Big Data with PySpark and AWS - Finding Min and Max

This video tutorial explains how to find the minimum and maximum ratings for movies using a dataset. It covers data preparation by converting strings into key-value pairs, and demonstrates the use of the 'reduce by key' function to calculate min/max values. The tutorial includes writing a lambda function for the calculation and explains the iterative process of reduction. The video concludes with an implementation of the solution.

How do we determine which value is minimum when comparing two ratings?

What is the final output when calculating the minimum rating for a movie?

How does the process of finding maximum ratings differ from finding minimum ratings?

What understanding should one develop regarding the reduction process in this context?
