Background In September 2019, AWS announced the general availability of QLDB, a fully managed centralised ledger database. At the heart of QLDB is its append-only journal. All requests go through the journal first, and it only contains committed transactions. This data is immutable, and creates a complete audit trail of every single change ever made - essential in a digital world that needs trust in the data, and must meet regulatory compliance.
