## What it is
A Java demo project built on Spring Cloud Netflix that illustrates a distributed transaction solution based on the TCC (Try-Confirm-Cancel) pattern, presented as a 'TCD' variant with Try-Confirm-Diagnose flow. It includes an Order/Account/Product microservice scenario with coordinator and lazy participant roles, C4 model diagrams, and Docker-based MySQL setup.

## Use cases
- learn how to implement TCC distributed transactions in microservices
- see a Spring Cloud Netflix example of try-confirm-cancel transactions
- understand how to handle eventual consistency across microservices
- study a TCC coordinator and participant reference implementation
- explore C4 model diagrams for a distributed transaction system
- find an alternative to 2PC for microservice transactions

## When to choose
- you want a worked example of TCC/TCD transactions on Spring Cloud
- you need to learn distributed transaction patterns with idempotency and conflict diagnosis
- you prefer a white-box coordinator embedded in business services over a separate transaction coordinator

## When to avoid
- you need a production-ready, actively maintained distributed transaction library
- you require a license-compliant dependency (no license is provided)
- you use non-JVM stacks or need protocol-agnostic middleware
- you want a reusable black-box transaction coordinator service
