Since pipeline validation uses a sample of data for data preview, some organizations may wish to prevent that data from being visible. Use the Disable button here to turn off data preview pipeline validation. Once disabled, the Validate pipeline icon on the Designer toolbar will be grayed out.
When copying, moving or importing a pipeline, opening pipeline in the canvas, or logging in, auto-validation will not be triggered. It will be triggered only when saving the pipeline, a Snap inside the pipeline, or the pipeline properties.
