You can configure which Snaplex a Pipeline will use in one of the following ways:
With a Pipeline open in Designer, you can select from the Snaplex drop-down menu a Snaplex on which the Pipeline should run.
When you configure a Scheduled or Triggered Task, you can select the Snaplex to run the Pipeline.
When using the Pipeline Execute Snap,
The Pipeline Execute Snap has a Snaplex field that specifies the child Pipeline’s Snaplex. leave the field blank.
As an alternative, use the pipe.plexPath expression to ensure that the child Pipeline runs on the same node as the parent.
if you specify a different Snaplex to run a child Pipeline, then the input documents and Pipeline parameters are passed through the Control Plane using encrypted transport to a node in the designated Snaplex.
You can improve performance by running a parent and child Pipeline on the same Snaplex node because data is not transferred over a network.
To set a dedicated Snaplex for a project, an Org admin can move a Snaplex from the Shared project to any other project. Only those Pipelines within the new project have access to that Snaplex.
