| **Create an IoT Analytics Pipeline** | |
| The following ``create-pipeline`` example creates a pipeline. A pipeline consumes messages from a channel and allows you to process the messages before storing them in a data store. You must specify both a channel and a data store activity and, optionally, as many as 23 additional activities in the ``pipelineActivities`` array. :: | |
