## What it is
Turbo is a lightweight Java-based workflow/flow engine framework compatible with BPMN 2.0, serving as the backend engine for low-code platforms. It provides core capabilities for flow definition, deployment, execution, submission, rollback, and execution trace tracking with minimal database tables.

## Use cases
- build approval workflows like leave request flows
- orchestrate after-sales or order refund processes
- power low-code platform workflow backends
- embed a reentrant flow engine in a Java application
- implement service orchestration with rollback support
- track and snapshot flow instance execution history

## When to avoid
- you need a full OA workflow platform with rich ecosystem, scripting, and multi-database support
- you need pure in-memory, stateless rule execution (Compileflow-style)
- your stack is not Java or you don't use MySQL
- you need standalone server deployment rather than an embedded library

## Facets
- artifact type: framework
- maturity: active
- function: workflow-automation, middleware, developer-tools
- domain: backend, developer-tools, apis
- platform: jvm, self-hosted
- tags: bpmn, flow-engine, low-code, approval-flow, service-orchestration, lightweight, automation
