An introduction to Amazon QLDB
AWS (Dan Blaner) and Leading EDJE (Andrew May) presented an introduction to Amazon QLDB with an example of using QLDB for event-sourcing on June 16, 2021.
Amazon QLDB is a Ledger database that provides an immutable history of the changes to your data. QLDB provides a cryptographically verifiable transaction log that cannot be modified, creating an unfalsifiable history of every transaction committed to the database. It is a serverless pay-as-you-go document database that can be queried using a SQL-like query language.
