CloudFlow:Wait steps

Last Updated:Oct 30, 2023

This topic describes wait steps and related examples.

Overview

A wait step pauses a flow execution for a period of time before proceeding. You can select a relative time or use a timestamp to specify an absolute end time.

A wait step contains the following attributes:

  • type: Required. The step type. The value wait indicates that the step is a wait step.
  • name: Required. The step name.
  • duration: Optional. The relative time to wait in seconds. It can be a constant or a parameter in the input. For example, 10 indicates waiting for 10 seconds, and $.sleep indicates that the wait time is obtained from the input sleep key. You must specify either duration or timestamp.
  • timestamp: Optional. The absolute time to wait in RFC3339 format. It can be a constant or a parameter in the input. For example, 2019-05-02T15:04:05Z indicates waiting until 15:04:05 on May 2, 2019 UTC. If the time is earlier than the current time, the wait step ends.
  • end: Optional. Specifies whether to proceed with the subsequent steps after the current step ends.
  • inputMappings: Optional. The input mappings.
  • outputMappings: Optional. The output mappings. A wait step does not generate data, and its $local is empty.
Note The maximum wait time is limited to two days.
