Wow,thanks for your support!
This issue is pending, because the new version of configuration API is under discussion.
Besides this,layotto has many things to do:

• add integration test;
• add document on how to use layotto(currently we only have some quickstart demo,but that's not enough);
  ......

And I'm preparing for new community tasks this week:

• add nodejs sdk
• add python sdk
• add c/c++ sdk
• add .net sdk
• add more sdk api into java sdk
• add more unit test whereever you like to make layotto's unit test coverage higher(currently it's only 45%)
• use other components to implement distributed lock API (mongo,cassandra,consul,etc.)

Let me add integration test first. Is there anything I should pay attention to?

抱歉等这么久才回，因为我在研究该咋加集成测试，目前看来有点麻烦，得在github action的workflow中部署多个docker镜像，包含我们依赖的所有组件（redis,etcd,zookeeper等）然后再运行各种demo、判断有没有报错。

我怕你不熟悉项目，搞这个会很难上手，要不我来搞这个，你看下有没有其他感兴趣的任务？

我在 #108 又加了一些任务，包括：

• 测试类：为runtime/runtime.go和grpc/api.go添加单元测试。这两个文件是layotto的核心引擎代码，各自负责组件生命周期管理（启动、注册、初始化）和grpc请求处理，完成此任务可以很好的了解Layotto架构
• 文档类：为各类API新增接口文档、新增sdk使用文档（我最近肝了很多文档感觉还是不够……）

我先来搞一下这两个文件的单测，后面再来看看怎么完善文档
