@BewareMyPower @merlimat The `MessageId` is used for identifying the position within a topic. For a partitioned topic, the `MessageId` includes the partition index for identifying the "position" within a partitioned topic. acknowledgementCumulative on a partitioned topic means acknowledging cumulative the messages of the partition inferred by the MessageId. This is semantically correct and there is no confusion here. It is the same concept as we usually say ordering is guaranteed using failover consuming a partitioned topic. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
