A large e-commerce company is looking to improve the search and recommendation capabilities on its platform. The company's data engineering team has recently built a data lake on Amazon S3, consisting of user interaction logs, product catalog information, and transactional data. The data is ingested from various sources, including RDBMS exports, streamed clickstream data, and batch processed log files, resulting in diverse data formats such as JSON, CSV, and Parquet.
The team wants to leverage this data for advanced analytics and machine learning but is facing challenges in consistently cataloging and querying this data efficiently. Additionally, they need to manage frequently evolving schemas as new product attributes and user interaction types are introduced.
How should the team use AWS Glue to address these challenges?
