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;
