CloudFlow:Standard mode and express mode

Last Updated:Sep 12, 2024

CloudFlow allows you to create a workflow in standard mode or in express mode. This topic describes how to select a mode to create workflows for your business.

Terms

  • Standard mode: This mode is suitable for conventional offline workflow orchestration and execution. This mode supports the persistent storage of execution step status and the execution status circulation of long-running workflows.

  • Quick mode: This mode is suitable for common online workflow orchestration and quasi-real-time workflow orchestration in latency sensitive and load intensive scenarios such as microservices API orchestration, glue layer API orchestration, and stream processing.
