AWS Glue examples using SDK for Rust

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for Rust with AWS Glue.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.

Get started

The following code examples show how to get started using AWS Glue.

Scenarios

The following code example shows how to:

  • Create a crawler that crawls a public Amazon S3 bucket and generates a database of CSV-formatted metadata.

  • List information about databases and tables in your AWS Glue Data Catalog.

  • Create a job to extract CSV data from the S3 bucket, transform the data, and load JSON-formatted output into another S3 bucket.

  • List information about job runs, view transformed data, and clean up resources.
