Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If TCC (Try-Confirm/Cancel) is used to control distributed transactions among microservices, then transaction consistency can be ensured, but external services that lack Try/Confirm/Cancel functions cannot be included in the distributed transaction control
Solution Approach 1:
The patent introduces a transaction coordinator as an intermediary component that mediates between microservices and external services. The coordinator handles the Try/Confirm/Cancel protocol for microservices while separately managing external services through a different mechanism (holding execution results and coordinating compensation), thereby enabling external services without TCC functions to be included in distributed transactions without compromising consistency
Solution Approach 2:
The patent segments the transaction control mechanism into two independent parts: one for microservices (using TCC with Try/Confirm/Cancel) and another for external services (using execution result holding and compensation coordination). This segmentation allows each service type to be handled according to its capabilities while maintaining overall transaction consistency
2Reliability
If optimistic parallelism control is used for CRUD type data stores, then strong consistency can be ensured, but external services with REST API function specifications cannot be controlled
Solution Approach 1:
The patent creates a universal transaction control mechanism that can handle multiple service types (CRUD data stores and external REST API services) through a unified approach. The transaction coordinator implements a general framework that adapts to different service interfaces, allowing external services with REST API specifications to be included while maintaining strong consistency through centralized coordination

AI summary
Provided is a microservice distributed transaction control method enabling an external service that can cooperate to be expanded more than before according to functionality of an external service. An external service 131 is classified into a plurality of types according to a difference in how a function related to a trial request is provided, and executed are a step of specifying a type of the external service 131 cooperating from a description of an external service cooperation processing designation 132, a step of selecting a transaction control unit adapted to a type of the cooperating external service 131 from a plurality of transaction control units 111 to 114 individually adapted to the plurality of types of the external service 131, and a step of executing transaction control between the microservice 104 and the cooperating external service 131 by applying the selected transaction control unit.
