Amazon S3 C++ SDK code examples using S3CrtClient

Purpose

The code examples in this directory demonstrate how to work with the Amazon Simple Storage Service (Amazon S3) using the AWS SDK for C++.

Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance.

This example uses the S3CrtClient for better upload/download performance over the S3Client. For other classes provided by the AWS SDK for C++ that also interface to Amazon S3, see example folder s3 and example folder transfer-manager.

Code examples

This is a workspace where you can find AWS SDK for C++ S3 examples utilizing the S3CrtClient.

⚠ Important

  • We recommend that you grant this code least privilege, or at most the minimum permissions required to perform the task. For more information, see Grant Least Privilege in the AWS Identity and Access Management User Guide.
  • This code has not been tested in all AWS Regions. Some AWS services are available only in specific Regions.
  • Running this code might result in charges to your AWS account.
  • Running the unit tests might result in charges to your AWS account. [optional]

Running the Examples

Before using the code examples, first complete the installation and setup steps of Getting Started in the AWS SDK for C++ Developer Guide. The Getting Started section covers how to obtain and build the SDK, and how to build your own code utilizing the SDK with a sample "Hello World"-style application.

Next, see Getting started with the AWS SDK for C++ code examples for information on the structure of the code examples, building, and running the examples.

If you want to demonstrate multipart upload, you will need a large enough file. You can download census data, "ny.json", from https://nara-1940-census.s3.us-east-2.amazonaws.com/metadata/json/ny.json.

See Amazon S3 code examples in the AWS SDK for C++ Developer Guide for additional information on using the Amazon S3 service with the SDK.
