Tcc Transaction
Este proyecto es una implementación en Java del patrón try-confirm-cancel, proporcionando un framework de transacciones distribuidas y una librería de gestión. Funciona como un coordinador que gestiona el ciclo de vida de transacciones de múltiples fases para garantizar la consistencia en múltiples servicios distribuidos.
El framework incluye un servidor coordinador de transacciones distribuidas que descarga operaciones de eventos y tareas de los servicios locales. También proporciona un panel dedicado para visualizar el estado de las transacciones y operar manualmente eventos y tareas distribuidas.
El sistema gestiona la consistencia a través de un protocolo de confirmación de tres fases y un mecanismo de reintento asíncrono para lograr la consistencia eventual. Admite almacenamiento backend conectable para persistir estados de transacciones y utiliza un flujo de trabajo basado en tareas para ejecutar operaciones distribuidas.
Features
- Distributed Transaction Coordinators - Acts as a central coordinator managing the lifecycle of multi-phase distributed transactions.
- Eventual Consistency Orchestrators - Orchestrates eventual consistency by retrying confirmation and cancellation phases until all participants synchronize.
- Three-Phase - Utilizes a three-phase commit protocol to separate asset reservation from the final commit or rollback.
- Distributed Transaction Management - Manages data integrity across distributed services via a coordinated three-phase workflow.
- Distributed Transaction Patterns - Implements the Try-Confirm-Cancel pattern to maintain consistency across multiple service boundaries.
- Try-Confirm-Cancel Implementations - Implements the Try-Confirm-Cancel (TCC) pattern for coordinating consistency across distributed services.
- Java Transaction Libraries - Provides a Java library for persisting transaction states and managing event-driven workflows.
- Transactional Storage Layers - Provides a transactional storage layer to save event and task data.
- Transaction State Persistences - Persists distributed transaction transition states in external databases or in-memory caches.
- Pluggable Storage Backends - Supports multiple database implementations for persisting transaction states through a pluggable interface.
- TCC Workflow Executions - Decomposes complex distributed transactions into individual tasks processed according to the TCC lifecycle.
- Transaction Management - Offers a central server to manage and monitor the lifecycle of asynchronous distributed transactions.
- Automatic Retry Mechanisms - Implements automatic retry mechanisms to ensure confirmation or cancellation phases eventually complete.
- Distributed Transaction Dashboards - Provides a dedicated visual dashboard for observing and manually operating distributed transaction tasks.
- Distributed Transaction Monitors - Ships a visual dashboard for monitoring and manually operating distributed transaction events and tasks.
