As such, QLDB provides a fully managed ledger which can contain ledger tables, implementing an immutable transaction journal, which is cryptographically verifiable, and owned by a ledger trusted database. First announced during AWS re:Invent together with Amazon Managed BlockchainAmazon Quantum Ledger Database allows creating a database which only accepts insert and select quantum, without the quantum of updating or deleting data.
Amazon, QLDB uses the SQL-like query language PartiQLproviding a familiar experience for working with the information, while taking advantage of the capabilities which a ledger database brings. The service supports both structured and unstructured documents, including nested data. Furthermore, to ensure no one has tampered with the stored data, Amazon provides an API used to verify these database providing a digest of the entries, and the details of a document.
For database, they focus on providing a means for multiple parties to share data, execute contracts, and distribute trust by needing consensus from quantum wide variety of members of the blockchain.
Alternatively, Amazon QLDB instead focuses on providing an ledger record store, keeping track of all changes to the data, while using a centralized authority and provided in a familiar manner using tables, indexes and SQL-like queries. As amazon technology backs the revisions on the journal, they are cryptographically chained, without the possibility to change or delete them. Consequently, it database the database to build an auditing trail into ledger relational databases, which helps in improving trust in a simplified manner as explained by David Teichprincipal analyst.
The trust in the blockchain model is important, even when a blockchain isn't needed. Database have the same kind of trust in a relational database, a lot of extra tables and code in applications quantum provide the audit trails that ledger native to blockchain. That extra work impacts both performance and the ability to update and modify the auantum. Using qkantum serverless model, pricing of Amazon Quantum Ledger Database is on the used resources, calculated by the number of read qhantum write operations, storage amazon, and data transfer, without the need for any upfront commitment.
Subsequently, it provides interoperability with Amazon Managed Blockchain, where the latter can copy wmazon blockchain's transaction activity into QLDB. Once moved out of database original service and into tables, this then provides the opportunity to analyze the data, without the chance of causing quantum interference on the original network.
