Qldb

Overview

Module

• package: org.eclipse.dirigible.sdk.qldb
• source: qldb/Qldb.java

Entry point to Amazon QLDB (Quantum Ledger Database) - the platform's append-only, cryptographically-verifiable ledger backend. open(ledger, table) returns a platform QLDBRepository pinned to a specific ledger and table; the returned object exposes the full insert / get / update / delete / history surface.

Suitable for any data set that must keep an audit trail of every change - financial ledgers, regulatory submissions, certified document chains. For regular CRUD without the audit trail, prefer org.eclipse.dirigible.sdk.db.Database on a traditional RDBMS.

Key Features:

• Ledger-backed Repository: open(ledger, table) returns a QLDBRepository pinned to one ledger / table pairing.
• Append-only with audit trail: Every change is recorded immutably and is cryptographically verifiable.
• Full CRUD + History: The returned repository exposes insert / get / update / delete and history operations.

Example Usage:

import org.eclipse.dirigible.sdk.qldb.Qldb;
import org.eclipse.dirigible.components.api.qldb.QLDBRepository;

QLDBRepository ledger = Qldb.open("CertifiedDocuments", "Documents");

// Insert / get / update / delete / history calls are exposed by QLDBRepository.

Methods
