Seata TCC Mode
TCC Mode is a distributed transaction solution supported by Seata that allows fine-grained control by business entities. It is an intrusive solution, meaning it directly impacts the service layer, independent of the underlying database. TCC Mode is the second transaction mode supported by Seata, initially contributed by Ant Financial. Its distributed transaction model operates directly on the service layer, does not rely on the underlying database, offers flexibility in choosing the granularity of business resource locking, reduces resource lock holding time, exhibits good scalability, and is designed for independently deployable SOA services.
In this document, we will focus on the usage of Seata TCC Mode. If you are interested in the principles behind TCC Mode and want to understand how Seata TCC addresses idempotence, empty rollback, and hanging issues, please refer to the corresponding Developer Guide.
TCC is entirely independent of the underlying database, allowing for the management of resources across databases and applications, providing more granular control to business entities.
