Repository Introduction

Seata Seata is an open-source distributed transaction solution that delivers high performance and user-friendly AT, TCC, SAGA, and XA transaction modes to ensure data consistency in microservices architectures.

Core Features of Seata:

1. Multi-Transaction Mode Support

   • AT (Auto-Compensation): Based on local transactions + global locks, offering high performance and low intrusion, suitable for most scenarios.
   • TCC (Try-Confirm-Cancel): Implements two-phase commit through business coding, ideal for high-consistency requirements.
   • SAGA: A long-transaction solution that orchestrates services via state machines, supporting eventual consistency.
   • XA: Based on the XA protocol, ensuring strong consistency but with lower performance.

2. Global Transaction Management

   • Coordinates distributed transactions through TC (Transaction Coordinator), managing branch transaction commits/rollbacks uniformly.

3. High Availability & Scalability

   • Supports cluster deployment, with TC registrable to Nacos, Eureka, and other service discovery platforms.
   • Storage modes include DB, Redis, etc., adapting flexibly to diverse scenarios.

4. Low Intrusiveness

   • Minimal code intrusion via proxied data sources (AT mode) or annotations (TCC/SAGA).

5. Strong Consistency Guarantee

   • Global lock mechanism prevents dirty writes, while AT mode auto-generates reverse SQL for data compensation, ensuring atomicity.

6. Ecosystem Compatibility

   • Compatible with Dubbo, Spring Cloud, gRPC, and other microservices frameworks, supporting MySQL, Oracle, PostgreSQL, and other mainstream databases.

Summary: Seata, with its flexible transaction modes, highly available architecture, and low-intrusion design, is a core tool for resolving distributed transaction challenges.
