Consumer Groups

The Consumer Groups step appears only when MirrorMaker 2 or Cluster Link is selected as the replication tool and the Sync Consumer Groups option was enabled during Cluster Setup. This step is not shown for WarpStream Orbit (which handles consumer group configuration within its Core Configuration step) or Replicator (which does not support consumer group synchronization via this step). This step determines which consumer groups will have their offsets synchronized to the destination cluster.

Consumer Group Overview

A top panel summarizes the consumer group landscape:

Metric	Description
Compatible Groups	Consumer groups that can be synchronized without issues.
Conflicting Groups	Consumer groups that have conflicts with the destination cluster (for example, groups already present on the destination with different configurations).

Selection Methods

Manual Selection

Use the checkboxes next to each consumer group to select individual groups for offset synchronization.

Pattern Matching

Enter wildcard patterns to select consumer groups by name:

Pattern	Result
app-*	Selects all groups starting with “app-”.
prod-*	Selects all groups starting with “prod-”.

Exclusion Patterns

Define patterns to exclude specific consumer groups:

Pattern	Result
*-internal	Excludes groups ending with “-internal”.
*-test	Excludes groups ending with “-test”.

Selection Summary

The Selection Summary panel updates in real time:

Field	Description
Groups Selected	The count of consumer groups currently selected for synchronization.
Compatible Status	An overall indicator showing whether all selected groups are compatible with the destination cluster.

Use the Search bar and Visible Filter to navigate large lists of consumer groups.

Caution

This step is only available for MirrorMaker 2 and Cluster Link jobs. WarpStream Orbit handles consumer group synchronization within its Core Configuration step (all or none), and Replicator does not support consumer group sync through this wizard step.
