> MirrorMaker can't guarantee data is consistent between clusters although the topic partition Numbers are equal.
> If we want to copy data from the old cluster to the new cluster, at the same time guaranteeing the data consistency, we have no choice but to code a MirrorMakerMessageHandler type of class manually to achieve it.
> I think we can add a parameter to say whether or not you want to ensure the order, such as data.consistency and default value is true.
> Of course, you can set data.consistency = false, if you don't want the data in order between clusters or some topic partition Numbers are not equal between clusters.
