Consumer Groups Reference

Use consumer groups to manage custom rate limiting configuration for subsets of consumers.

The consumer_groups endpoint works together with the Rate Limiting Advanced plugin. To use consumer groups for rate limiting, configure the plugin with the enforce_consumer_groups and consumer_groups parameters, then use the /consumer_groups endpoint to manage the groups.

For more information and examples of setting up and managing consumer groups, see the Consumer Groups examples.

Note: Consumer groups are not supported in declarative configuration with decK. If you have consumer groups in your configuration, decK will ignore them.
