# AWS Glue Samples



AWS Glue is a serverless data integration service that makes it easier to discover, prepare, move, and integrate data from multiple sources for analytics, machine learning (ML), and application development.

This repository has samples that demonstrate various aspects of the [AWS Glue](https://aws.amazon.com/glue) service, as well as various AWS Glue utilities.



You can find the AWS Glue open-source Python libraries in a separate repository at: [awslabs/aws-glue-libs](https://github.com/awslabs/aws-glue-libs).
