Amazon Quantum Ledger Database (Amazon QLDB) launches increased performance and latency reduction for control plane verification APIs. With this improvement, QLDB customers will experience an average latency reduction of up to 70% and the ability to scale at least 10 times from the current call volumes in many scenarios.
Amazon QLDB verification APIs - getDigest, getRevision, and getBlock - allow customers to cryptographically prove that data stored in QLDB has not been changed. When combined with built-in document immutability and versioning of all changes, QLDB reduces complexity and cost to add audit and data validation capabilities to applications for which data integrity and provenance are important. With the performance improvements announced today, customers may increase the volume of documents verified in audit scenarios by an order of magnitude.
Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log owned by a central trusted authority. You can use QLDB to track all application data changes, and maintain a complete and verifiable history of changes over time.
