description AWS Glue Overview

help AWS Glue FAQ
What is AWS Glue used for?
AWS Glue is a managed service for discovering, transforming, and moving data between sources. It is commonly used to prepare data for analytics systems and data lakes on Amazon Web Services.
What is the AWS Glue Data Catalog?
The Data Catalog is a central metadata repository that records information such as tables, schemas, and locations. Services such as Amazon Athena can use that metadata to query data stored in places such as Amazon S3.
Does AWS Glue require users to manage servers?
Glue is managed by AWS, so users do not maintain the underlying ETL infrastructure in the same way they would with self-hosted servers. They still configure jobs, permissions, schedules, connections, and costs.
Can AWS Glue generate ETL code?
Yes, Glue can provide code-generation and visual job-building features, while also supporting custom scripts for more control. The generated job still needs testing against the real source data and target schema.
