Designer settings
The Admin Manager Design option in the navigation pane provides controls for:
- The environment-wide pipeline validation setting.
- The number of documents shown in Snap data previews when validation is enabled.
Pipeline validation
The environment-wide pipeline validation setting controls whether the SnapLogic Platform validates pipelines by running a sample of data through the Snaps when you validate or save a pipeline. When validation is disabled, pipelines are still saved, but Snaps do not execute and no preview data is generated.
Environment admins can enable or disable pipeline validation for the entire environment in Admin Manager. When validation is enabled, users can view data previews in the Designer, subject to the data preview limits and required permissions described below.
Data preview
When pipeline validation is enabled, the SnapLogic Platform attempts to pass a sample of real data through pipeline Snaps on validation or save. Snaps that execute successfully provide preview data. Data preview shows whether pipeline mappings and transformations are working as expected.
How Data Preview works
The SnapLogic Platform encrypts data before storing it to use in data preview. By default, the data preview includes the first 50 records from the input source, up to 15 MB in total size. If the number of documents to preview exceeds 15 MB, validation causes an error. Environment admins can change the environment setting for preview documents in Admin Manager. Users can change the number of preview documents for their own account in user settings, up to the value set by the Environment admin.
Required permissions
To view the data preview, you must have execute permissions to the pipeline. If you have read, write, or read and write permissions to the pipeline, the data preview does not display. Permissions to pipelines and other assets are assigned at the project level. Refer to Assign permissions.
