The configuration can be set to the fully qualified class name of a custom task assignor + implementation that has to extend the new + <code>org.apache.kafka.streams.processor.assignment.TaskAssignor</code> interface. + + The new configuration also allows users to bring back the behavior of the old task assignor + <code>StickyTaskAssignor</code> that was used before the introduction if + <code>HighAvailabilityTaskAssignor</code>. If no custom task assignor is configured, the default task assignor + <code>HighAvailabilityTaskAssignor</code> is used. + + This change also removes the internal config <code>internal.task.assignor.class</code> that was used for the same + purpose. If you were using this config, you should switch to using <code>task.assignor.class</code> instead.
