SmartEngine is a lightweight business orchestration engine. It's used widely in Alibaba Group. It can be used to orchestrate multiple service in microservice architecture, start/signal a process instance in a very high-performance way with low-storage cost, and also can be used in traditional process approval scenarios.

0. KISS(Keep It Simple, Stupid)
1. Standardization: embrace BPMN2.0, specify ubiquitous language.
2. Extensible: such as parser,behavior, storage, user integration etc.
3. High Performance: provide a simple way to improve performance and reduce storage cost in some simple process scenarios.
4. Less Dependent: at the very beginning, we try our best to avoid JAR hell.

0. CQRS-style APIs to start, signal, query process instance, task, activity.
1. Support basic BPMN symbols : StartEvent,EndEvent,SequenceFlow,ExclusiveGateway,ServiceTask,ReceiveTask.
2. Provide a simple way to improve performance and reduce storage cost in some simple process scenarios.
3. Other: Process Jump; VariablePersister; TaskAssigneeDispatcher; Countersign.
