Child flows of Serverless Workflow To reduce flow complexity, a flow is divided into multiple child flows. Flows can be reused more easily. You can put some common steps in a flow and reuse these steps in other flows. This feature breaks some limits of a flow, such as the maximum number of events (5,000 by default) and the maximum execution time (1 year). Error handling is implemented for the overall output of the flow. For example, you can design a parallel step as a child flow and handle errors that occur in the execution of the child flows in the parent flow. 2020-02-29 Child flows of Serverless Workflow

By integrating Message Service (MNS) queues, Serverless Workflow allows all applications that can access message queues to be part of a flow and cooperate to achieve business objectives. 2019-11-01 Integrate MNS and use callback to orchestrate any type of tasks
