¶ Description
Sleep for a while.
¶ Parameters
¶ Parameters tab
Parameters:
- Developer mode: activate/deactivate code tab.
- Ms to Sleep Number of milliseconds to pause the pipeline execution. For example,
5000will pause for 5 seconds. - Optional: wait for this file to appear (optional)*: If set, the action waits for the specified file to become available before or during the sleep period. Useful to ensure file availability from asynchronous systems.
¶ Description tab
See dedicated page for more information.
¶ Code tab
sleep is a scripted action. Embedded code is accessible and customizable through this tab.
¶ Configuration tab
See dedicated page for more information.
¶ About
The sleep action pauses pipeline execution for a defined duration. This is particularly useful in ETL workflows where a delay is needed to:
- Wait for asynchronous external processes to complete (e.g., file writing, file transfer).
- Introduce intentional buffering to avoid overwhelming resources.
- Synchronize the sequence of actions when dependencies rely on time gaps.
In addition to sleeping for a specified time, this action optionally supports waiting for a file to appear in the file system. This ensures proper timing when dealing with generated resources (such as downloads or logs) before proceeding to the next action.
¶ Example Usage
¶ Use Case: Wait 5 seconds before continuing
- Add the sleep action after an upstream action (e.g., downloading files).
- Set
msToSleepto5000. - Leave the
filenamefield empty if no file check is needed. - Run the pipeline.
Notes:
- If both
msToSleepandfilenameare set, the pipeline pauses for the full duration or until the file is detected, whichever is longer.- This action introduces a delay without consuming significant resources.
