Seata
Seata is a distributed transaction coordinator and consistency framework designed to maintain data integrity across multiple microservices. It functions as a manager that synchronizes state across separate databases to ensure atomic commits or rollbacks of global transactions.
The project provides a toolkit for implementing distributed transaction patterns, using a two-phase commit protocol and centralized status tracking to prevent data anomalies. It orchestrates eventual consistency through state-machine-based tracking and message-driven coordination to handle timeouts and failures in distributed workflows.
The framework coordinates the lifecycle of branch transactions and utilizes undo logs to reverse changes if a distributed transaction fails. It manages resource-level locking during the prepare phase to prevent concurrent modifications until a global decision is reached.
Features
- Distributed Transaction Coordinators - Provides a centralized coordinator to manage the lifecycle of global transactions across multiple microservices.
- Consistency Frameworks - Provides a comprehensive framework for maintaining data consistency across microservices using distributed transaction patterns.
- Two-Phase Commit - Uses a prepare and commit process to synchronize state across independent services.
- Undo Logs - Utilizes undo logs to store before-image data and reverse changes if a distributed transaction fails.
- Data Synchronization and Consistency - Coordinates transactions across multiple services to ensure all participants commit or roll back together.
- Distributed State Management - Synchronizes state across separate databases using centralized status tracking to maintain data integrity.
- Commit Protocols - Implements a two-phase commit protocol to coordinate atomic updates across distributed services.
- Distributed Transaction Management - Implements distributed transaction management to ensure data integrity across multiple separate databases.
- Database Record Locks - Implements resource-level locking during the prepare phase to prevent concurrent modifications until a global decision is reached.
- Distributed State Synchronizers - Tracks the status of branch operations across services to synchronize business logic and data state.
- Transaction State Tracking - Tracks the progression of global and branch transactions through defined states to handle timeouts and failures.
- Rollback Workflows - Manages the complex process of rolling back distributed changes when a global transaction fails.
- State Machine Orchestrators - Uses state-machine orchestration and message-driven coordination to handle failures in distributed workflows.
- Distributed Transactions - Distributed transaction services for microservices.
