AWS QLDB demo

Abstract

Amazon Quantum Ledger Database (Amazon QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log.

For this demo I use amazon-qldb-driver-rust. I decided to use this crate because the API it provides is much simpler than aws-sdk-qldb and aws-sdk-qldbsession.

This demo shows how to work with qldb using Rust, specifically:

• how to create tables;
• insert data;
• delete data;
• and query;

Result

Try it out!

1. Create ladger with name kawasaki.
2. Install Rust.
3. Set up enviroment variables:

• Windows:

setx AWS_ACCESS_KEY_ID your_access_key_id
setx AWS_SECRET_ACCESS_KEY your_secret_access_key
setx AWS_DEFAULT_REGION default_region

• Linux

export AWS_ACCESS_KEY_ID=your_access_key_id
export AWS_SECRET_ACCESS_KEY=your_secret_access_key
export AWS_DEFAULT_REGION=default_region

• Or create an .env file and change these variables there.

4. Run the app

cargo run
