## What it is
Hmily is a financial-grade flexible distributed transaction framework for Java, supporting TCC, TAC, and XA transaction patterns. It integrates non-invasively with Spring Boot, Spring Cloud, Dubbo, Motan, and other RPC frameworks.

## Use cases
- ensure atomicity across microservices in Java
- implement TCC distributed transactions with Spring Cloud
- roll back distributed transactions on failure in Dubbo services
- prevent transaction suspension in financial systems
- add distributed transaction support to Spring Boot apps
- manage cross-service data consistency

## When to choose
- you need high-reliability distributed transactions in a Java/Spring microservices stack
- you use Dubbo, Motan, or Spring Cloud RPC and need TCC-style compensation
- financial-grade consistency and abnormal recovery matter

## When to avoid
- your application is a single monolith with one database - local transactions suffice
- you are not on the JVM
- you need a polyglot solution across non-Java services

## Facets
- artifact type: library
- maturity: active
- function: microservices, middleware, database, workflow-automation
- domain: microservices, backend, fintech
- platform: jvm
- tags: distributed-transactions, tcc, saga, xa, spring-boot, dubbo, spring-cloud, spring
