What Is Seata? The Open‑Source Distributed Transaction Solution for Microservices
Seata is an open‑source distributed transaction framework designed for microservice architectures, offering high performance and ease of use, with origins in Alibaba’s internal consistency middleware and now commercialized, and the article outlines its AT solution alongside a comprehensive Spring Cloud Alibaba tutorial covering Nacos, Sentinel, and Seata topics.
What is Seata
Seata is an open‑source distributed transaction solution that aims to provide high‑performance and easy‑to‑use transaction services in microservice architectures. Before being open‑sourced, Seata’s internal version served as Alibaba’s consistency middleware, supporting major business units during events such as Double 11, and later became a commercial product on Alibaba Cloud and Financial Cloud.
Scenarios for Distributed Transactions
Distributed transactions are needed when multiple microservices must maintain data consistency across service boundaries.
Seata AT Solution
The AT (Automatic Transaction) mode provides a simple way to achieve distributed transaction consistency.
