Overview

Pipeline properties refer to the configurable settings, variables, or inputs you use to customize the behavior of a pipeline. These parameters provide a means of making pipelines more adaptable, maintainable, and reusable by allowing you to configure their behavior without altering the core logic of the pipeline. When you add a new pipeline, you initialize its properties.

Pipeline Parameters

To update the properties of an existing pipeline, view the pipeline and click the Edit Pipeline Properties icon ( ) on the toolbar. Note that you cannot update all fields. The pipeline properties dialog includes the following tabs:

Settings

Label	Required. The name for the Pipeline. The Pipeline name must be unique within the Project and must not exceed 100 characters.
Project	Required. The Project in which you save the Pipeline, displayed as <project_space>/<project_name>. All necessary resources (such as files and Accounts) must be within the same Project unless they are part of the Shared project. You cannot update this property after you save your pipeline the first time. To change the Project later, you must move the pipeline to a new Project or make a copy.
Type	Standard. The default pipeline type. eXtreme. No longer supported.
Resumable Mode	Select this checkbox to convert your pipeline into a resumable pipeline, which pauses when an error occurs and can be resumed at the point of error later. Learn more: Resumable Pipelines
Error Pipeline	The pipeline that handles any error documents produced by this Pipeline.
Error Pipeline Parameters	Key-value pairs containing parameters to pass to the Error Pipeline if an error occurs.
Parameters	Key-value pairs containing parameters to pass to this Pipeline during execution. If the Capture checkbox is selected, the Pipeline parameter value is displayed in the Pipeline Execution Statistics window on SnapLogic Dashboard, when the Pipeline run is started by a Task or by another Pipeline using the PipeExecute Snap. The keys and values of a Pipeline parameter can contain alphanumeric characters only. You can also specify the values for the parameters within a Task that runs this Pipeline. To use the value of the parameter as part of an expression within a Snap, you must prefix the parameter name with the underscore character ( _ ). For example, if the parameter name is `myParam1`, you can refer to its value by using `_myParam1` as follows: `'/out' + _myParam1 + '.json'` To use the same account in multiple Pipelines, you can reference the account credentials using an expression in a Pipeline parameter value. IMPORTANT: Use pipeline parameters to pass metadata, not data. To pass data, use any of the following methods: Save the data to a file and then pass the filename as a pipeline parameter value. Use the Pipeline Execute Snap and pass the data through the input view of the child Pipeline. If you pass large data sets as parameter values, the following built-in limitations in the SnapLogic Platform can cause parameter values to be truncated or can prevent the Pipeline from running: If Capture is selected, the first 256 bytes of the captured Pipeline parameter value are stored in the runtime for debug purposes. Each Snaplex node pushes information to the control plane about all the Pipelines running on the JCC node, and this information is limited to 250MB for all Pipelines on the node. If the total size of the Pipeline parameter values for one Pipeline execution (including parameters that are not captured) exceeds 8 MB, the Pipeline does not execute.
Expression Libraries	The list of expression libraries to import and use with this Pipeline. Path: Path to the file that contains the expression to import. The path can be absolute or relative to the current project. As: The name to use for the library under the `lib` variable. Defaults to the base name of the file. Learn more: Expression Libraries
Cache Pipelines	The data to pre-cache in a Cache Pipeline. The alias and corresponding pipeline to run and store the data under the provided alias.. You can access this cache with Pipeline Cache properties, where you can call it from the cache and filter the conditions to return back the data specified by the function. This reference provides the full document from the match to then use the output from the target match.

TIP: You can use captured Pipeline parameter values and Error Pipeline parameter values to search for a Pipeline in the Pipeline wall on the Dashboard. For details, see Pipeline Search/Pipeline Filter.

Open API

You can use the Open API tab to add information, such as data type and description, about the Pipeline parameters. This information helps other Pipeline developers understand what each Pipeline parameter represents.

Pipeline parameters in this tab are populated after the Pipeline is saved. If you added new parameters since the last time you saved the Pipeline, save the Pipeline again to update this tab.

Key	The name of the Pipeline parameter as specified in the Parameters section (Key).
Type	The data type of the parameter. Choose one of the following data types from the dropdown list: string number byte binary boolean date date-time password Default value: string Learn more: Data Types
Description	A description of the parameter. This description is included in the auto-generated API document about the Pipeline’s properties. Default value: None
Required	Specifies whether the parameter is required. Default value: Not selected

Info

Notes	Additional information about this pipeline.
Purpose	The purpose of this pipeline.
Author	The creator of the pipeline. If you are adding a new pipeline, this field is prepopulated with your username or email address.
Doc Link	The link to the documentation about this pipeline (if any).
