Application Scenario
You can use this node to achieve the parallel running of multiple upstream nodes.
Coordinate nodes without lineage relationships: When the final output node in a business process receives inputs from multiple upstream nodes that are not interdependent, use a virtual node as the upstream node of these input nodes to coordinate the downstream nodes.
Manage multi-branch business processes: To enable cross-process dependencies in a business process with multiple branches, use a virtual node as an output node to aggregate these branches.
Function Description
Drag a virtual node to the design page and connect it with other nodes. No node configuration is required. The virtual node is mainly used to implement N:N relationships.
A virtual node is a no-op node that does not generate any data. (It does not consume resources or impede the running of downstream nodes.) It is typically used as the starting node of a business process or as the output node for aggregating nodes in multiple branches in a business process.

Example
For example, suppose two Data Synchronization nodes and two SQL Script nodes are on the design page. You want the two Data Synchronization nodes to be executed in parallel first, and then you want the data to be transferred to the two SQL Script nodes for synchronous processing.
In this case, drag a Virtual Node node to the page and connect it with other nodes based on the parallel execution relationship.
