Using DynamoDB Write Transactions with the AWS SDK for Rust

Amazon DynamoDB supports atomic write transactions, as well as get transactions. In this video, we'll explore how you can use the AWS SDK for Rust to perform several different types of actions against items in DynamoDB tables. Write transactions support put, update, delete, and conditional check actions. Each write transaction can mix and match up to 100 of these actions per request. Write transactions can span multiple DynamoDB tables, as long as they exist in the same AWS account and region. Transactions are also limited to 4 MB payloads. The DynamoDB batch APIs support up to 16 MB payloads. The primary benefit of transactions is atomicity, however.
