Labels Overview

Use labels to group engines. All engines of the same type that have the same label function as a group.

When you create a job, you assign labels to the job so Control Hub knows the group of associated engines to run the job on. For example, if you assign a sales label to a Transformer job, then the job can run on any Transformer with a sales label.

When applying labels, you can use any classification structure that you choose. For example, you might use labels to group Data Collectors by environment, to group Edge Data Collectors by project, and to group Transformers by department.

Important: Labels are case sensitive.

When you start a job, Control Hub runs one pipeline instance on an available engine by default. For example, if three Data Collectors have all of the specified labels for a job that contains a standalone pipeline, by default Control Hub runs one pipeline instance on the Data Collector running the fewest number of pipelines.

You can increase the number of pipeline instances that Control Hub runs for a job for Data Collector and SDC Edge pipelines. For Transformer pipelines, Control Hub runs a single pipeline instance for each job.

You can include one or more backup engines in a group to support pipeline failover for jobs.
