Merge Node

The Merge Node in Cobalt provides a fundamental functionality for combining multiple branches of a workflow into a single flow. This is particularly useful when there are parallel processes within a workflow that need to converge at a common point before proceeding with the subsequent actions. The Merge Node helps to simplify workflows by reducing the number of redundant nodes and ensuring a cleaner, more efficient workflow design.

​

Use Case for Merge

Consider a scenario where two parallel processes need to run simultaneously, and once both processes are completed, a common action or set of actions should be executed. So rather than replicating the same flow for each branch, leading to increased complexity and a higher number of nodes, the Merge Node allows these branches to converge seamlessly.

​

Example Scenario

• Parallel Processing: You have three branches/nodes running different processes in parallel.

• Convergence: Once all three branches complete their respective tasks, they need to converge to perform a common action, such as creating a datastore or any other action.

By using the Merge Node, you can bring both branches together, eliminating the need to duplicate the subsequent steps for each branch.
