EasyTransaction
EasyTransaction is a distributed transaction framework that coordinates data consistency and failover across independent microservices. It implements unified patterns such as SAGA, Try-Confirm-Cancel, and reliable messaging to handle multi-service operations and failures safely.
The framework combines diverse transaction styles and nests operations to manage complex workflows without relying on central coordinators. It includes an automatic compensation engine that executes reverse operations and rollback workflows sequentially when downstream failures occur, alongside an automated crash recovery mechanism that restores system state using write-ahead logs and status records.
Additional capabilities include dynamic data routing to select appropriate database replicas based on custom rules, logical idempotency guards to enforce execution uniqueness during retries, and modular extension interfaces for customizing communication protocols, serializers, and storage backends.
Features
- Distributed Transaction Management - Coordinates data consistency across microservices and distributed services using unified patterns like Try-Confirm-Cancel and SAGA.
- Transactional Storage Engines - Persists transaction state records in relational databases, caches, or files to enable system recovery and audit tracking.
- Write-Ahead Logging - Persists transaction states and phase records to durable storage before executing steps to guarantee recovery after crashes.
- Database Crash Recovery - Restores system state after unexpected crashes using write-ahead logs and status records to execute automatic rollbacks or confirmations.
- Automatic Compensation Mechanisms - Executes reverse operations and rollback workflows sequentially when downstream failures occur to maintain data consistency.
- Saga Coordinators - Manages data consistency and failover across multiple microservices using unified patterns like SAGA and Try-Confirm-Cancel.
- Try-Confirm-Cancel Protocols - Executes Try-Confirm-Cancel phases to maintain data consistency across distributed services.
- Distributed Transaction Managers - Coordinates data consistency across microservices using unified patterns like Try-Confirm-Cancel, SAGA, and reliable messaging.
- Distributed Transaction Patterns - Coordinates data consistency across independent microservices by applying multiple transaction patterns within complex workflows.
- Failure Recovery - Restores system state after crashes and handles automatic rollbacks or confirmations using persistent transaction logs.
- Operation Idempotency - Guarantees that business methods execute only once logically using built-in controls and order processing to prevent duplicate actions.
- Reliable Message Delivery - Ensures that distributed messaging tasks execute reliably and exactly once to prevent duplicate business actions.
- Workflow Idempotency Enforcers - Enforces execution uniqueness checks using persistent state records to prevent duplicate processing during retries.
- Complex Workflow Coordination - Combines diverse transaction styles and nests multiple operations to manage complex multi-service workflows without central coordinators.
