AWS Glue

AWS Glue is a fully managed ETL (extract, transform, and load) service that makes data preparation simpler, faster, and more cost-effective. It automatically discovers your data, generates transformation code, and runs ETL jobs on a serverless platform.
Core Benefits​
- Serverless: No infrastructure to manage; AWS Glue handles provisioning, configuration, and scaling of resources.
- Automated Code Generation: Can automatically generate ETL scripts to transform your data.
- Integrated: Tightly integrated with the AWS Glue Data Catalog, S3, and other AWS analytics services.
Role in Data Pipeline​
Data Processing: Serves as the primary ETL engine for cleaning, enriching, and transforming raw data from sources like S3 into a structured format suitable for analysis in a data warehouse or data lake.

Use Cases​
- Data Transformation: Converting raw, nested JSON data from an S3 data lake into a compressed, columnar Parquet format for efficient querying.
- Data Enrichment: Joining customer data with marketing data to create a unified dataset for analysis.
info
AWS Glue is the serverless solution for preparing and transforming data, removing the heavy lifting of managing ETL infrastructure.
