A Parallel Gateway is used to split a flow into multiple parallel paths (diverging), or to merge multiple parallel paths (converging). You can also use Parallel Gateways to converge and diverge at the same time.
A Parallel Gateway appears as a diamond shape with a plus sign marker.
A diverging Parallel Gateway splits the Process into multiple paths. All tasks on outgoing paths are performed in parallel.
A converging Parallel Gateway waits for all incoming tasks to complete before continuing the process.
You’ll find Parallel Gateway attributes within the Attributes panel, under the Attributes tab.
