Dtm
dtm ist ein Framework für verteilte Transaktionen und ein Workflow-Orchestrator, der darauf ausgelegt ist, Datenkonsistenz über Microservices hinweg zu verwalten. Es fungiert als zentraler Koordinator, der verteilte Transaktionen synchronisiert und den Status sowie den Ausführungsfluss komplexer Sequenzen verteilter Aufgaben verwaltet.
Das Framework implementiert verschiedene Koordinationsmuster, darunter Saga, TCC und XA, um Synchronisationsfehler zu vermeiden. Es bietet speziell einen sprachübergreifenden Transaktionskoordinator, um Operationen über Services hinweg zu synchronisieren, die in verschiedenen Programmiersprachen geschrieben sind, und nutzt eine zuverlässige Messaging-Outbox, um Datenbank-Updates mit dem Message-Dispatching zu koppeln.
Das Funktionsspektrum deckt die Wiederherstellung verteilter Systeme durch kompensierende Transaktions-Rollbacks, Two-Phase-Commit-Koordination und Exactly-Once-Message-Delivery ab. Die Infrastruktur unterstützt horizontale Kapazitätserweiterung und Hochverfügbarkeitskonfigurationen, um die Stabilität bei steigendem Anfragevolumen aufrechtzuerhalten.
Features
- Business Process Orchestration - Functions as a distributed workflow orchestrator that manages the execution flow of complex business processes.
- Distributed Workflow Orchestrators - Coordinates complex sequences of distributed tasks while managing their execution flow and state.
- Reliable Message Delivery - Implements exactly-once message delivery using a reliable messaging outbox to maintain data integrity across microservices.
- Automatic Compensation Mechanisms - Automatically invokes compensating operations for sub-transactions to restore system consistency after a failure.
- Distributed State Recovery - Automatically invokes compensating operations to roll back failed sub-transactions and restore system consistency.
- Distributed Transaction Coordinators - Provides a centralized coordinator to manage global transaction lifecycles and maintain data synchronization across microservices.
- Polyglot Coordinators - Provides a centralized coordinator that synchronizes distributed transactions across services written in different languages.
- Saga Coordinators - Coordinates saga-based distributed transactions by executing compensating transactions in reverse order during failures.
- Two-Phase Commit Protocols - Manages a two-phase commit protocol to ensure atomic updates across distributed data stores.
- Distributed Transaction Management - Ensures data consistency across microservices using distributed transaction patterns like Saga, TCC, and XA.
- Try-Confirm-Cancel Implementations - Coordinates the Try, Confirm, and Cancel phases to manage resource reservation in distributed business operations.
- Consistency Frameworks - Provides a comprehensive framework for maintaining data integrity and synchronization across distributed services.
- State Machine Orchestrators - Uses a persistent state machine to track the lifecycle and ensure consistent progress of distributed transactions.
- Transactional Outbox Patterns - Implements the transactional outbox pattern to ensure atomicity between database updates and event publishing.
- Domain Workflow Orchestration - Orchestrates complex sequences of distributed tasks to fulfill specific business use cases.
- Horizontal Scaling Deployments - Supports horizontal capacity expansion and high availability to maintain stability as request volumes increase.
- Event Driven Messaging - Provides an event-driven messaging layer to trigger asynchronous task execution across remote microservices.
- Outbox Pattern Implementations - Couples database updates with message dispatching to ensure exactly-once delivery and prevent data loss.
- Database Tools - Distributed transaction management service.
