Tcc Transaction
This project is a Java implementation of the try-confirm-cancel pattern, providing a distributed transaction framework and management library. It functions as a coordinator that manages the lifecycle of multi-phase transactions to ensure consistency across multiple distributed services.
The framework includes a distributed transaction coordinator server that offloads event and task operations from local services. It also provides a dedicated dashboard for visualizing transaction status and manually operating distributed events and tasks.
The system manages consistency through a three-phase commit protocol and an asynchronous retry mechanism to achieve eventual consistency. It supports pluggable backend storage for persisting transaction states and utilizes a task-based workflow to execute distributed operations.
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.
