Glue Data Catalog on Ubuntu 24.04

AWS Glue Data Catalog is a centralized, fully managed metadata repository that stores structural and operational metadata for data assets used across analytics, data engineering, and data science workloads. It enables users to easily discover, classify, and manage datasets stored in services such as Amazon S3, Amazon RDS, Amazon Redshift, and other AWS-supported data sources.

The Glue Data Catalog acts as a persistent metadata store that integrates seamlessly with AWS analytics services including Amazon Athena, Amazon EMR, AWS Glue ETL, and Amazon Redshift Spectrum. It simplifies schema discovery, enables consistent data definitions, and improves governance across large-scale data environments.

Features of AWS Glue Data Catalog:

• Centralized metadata repository for structured and semi-structured data.
• Automatic schema discovery using AWS Glue Crawlers.
• Seamless integration with Athena, EMR, Redshift, and Glue ETL.
• Supports data stored in Amazon S3, databases, and data warehouses.
• Enables data governance, cataloging, and schema versioning.
• Scales automatically with no infrastructure management required.

To verify AWS Glue Data Catalog access and configuration, use the following steps:

 Check AWS CLI version: $ aws --version

List available Glue databases:
$ aws glue get-databases --region us-east-1

List tables in a database:
$ aws glue get-tables --database-name  --region us-east-1

Disclaimer: AWS Glue Data Catalog is a managed cloud service provided by Amazon Web Services. Users are responsible for configuring AWS credentials, IAM roles, regions, crawlers, and permissions. Proper access control, encryption, and governance practices should be followed when managing metadata and data assets.
