Ingesting Data Using AWS Glue

You are a data engineer tasked with migrating some new CSV files into S3. Once there, you need to add the schema to Glue using Glue Crawler. The Data Science team would like to train some new models on a combined table of this information but only using a few select columns. To decrease cost and improve processing time, you need to create a job in Glue that will combine the CSV files together into one table but only including the needed columns. Then, you need to run the job and verify success in S3. After that, you will be ready to inform the Data Science team that the data is ready for training.
