Amazon QLDB
Amazon QLDB (Quantum Ledger Database) was a fully managed, serverless Amazon Web Services database service purpose-built and designed as a ledger database. AWS ended support for Amazon QLDB on July 31, 2025 — the service no longer accepts new ledgers, and its dedicated product and documentation pages have since been withdrawn (they now redirect to Amazon Aurora).
Key points
- Designed as a ledger database: maintained a complete, verifiable history of changes made to application data over time.
- Was fully managed and serverless, removing the need to provision servers or capacity.
- End of support was July 31, 2025. AWS recommends migrating existing workloads to Amazon Aurora PostgreSQL-Compatible Edition, using features such as pgAudit, Database Activity Streams, and Amazon S3 exports to reproduce QLDB’s journal, history, and streaming capabilities.
- Had been positioned as an alternative to building a custom ledger on top of a relational database such as Amazon RDS — a role now filled by Aurora PostgreSQL’s ledger-adjacent features.
