AWS’s chief evangelist Jeff Barr demonstrated how QLDB is set up and managed with other services, such as the AWS Command Line Interface, AWS Management Console (CLI), and CloudFormation templates in a blog post on Sept. 10. Barr explained that QLDB, a ledger database is intended to be an authoritative data source (often referred to as a system or record) for stored data. It preserves a complete and immutable history of all data changes that have been made to it. This history cannot be altered, deleted, or updated. QLDB supports PartiQL SQL queries on historical data and provides an API that allows cryptographically verify the authenticity and legitimacy of the history. It is available in the US East (Ohio), US East(N. Virginia), US West, Oregon, EU (Ireland) and Asia Pacific (Tokyo), with more regions coming soon.
