AWS SDK for Go V2 code examples for Amazon DynamoDB

Purpose

These examples demonstrates how to perform several DynamoDB operations using version 2 of the AWS SDK for Go.

Prerequisites

You must have an AWS account, and have your default credentials and AWS Region configured as described in Configuring the AWS SDK for Go in the AWS SDK for Go Developer Guide.

Running the code

DescribeTable/DescribeTablev2.go

This example lists the following properties of a DynamoDB table.

• Number of items
• Size, in bytes
• Status, such as Active

go run DescribeTablev2.go -t TABLE

• TABLE is the name of the table.

The unit test accepts a similar value in config.json.

Notes

• 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

Unit tests should delete any resources they create. However, they might result in charges to your AWS account.

To run a unit test, enter:

go test

You should see something like the following, where PATH is the path to the folder containing the Go files:

PASS
ok      PATH 6.593s

If you want to see any log messages, enter:

go test -v

You should see some additional log messages. The last two lines should be similar to the previous output shown.
