Overview

In this project, you'll assume the role of a data engineer working with a large dataset of loan data from Lending Club. Your challenge is to analyze this data efficiently given memory constraints. You'll apply techniques to optimize the DataFrame's memory usage and process the data in chunks. Throughout the project, you'll use Python and pandas to explore the data, identify opportunities to reduce memory usage, and implement changes like converting data types and using categories. You'll calculate memory usage to quantify improvements. This project lets you apply key data engineering skills to solve a realistic, large-scale data challenge. Objective: Efficiently analyze a large loan dataset by optimizing DataFrame memory usage and processing the data in chunks using Python and pandas.
