@yangy0000 @xhl1988 I look forward to your reply

Sorry it’s hard coded: https://github.com/uber/uReplicator/blob/master/uReplicator-Manager/src/main/java/com/uber/stream/kafka/mirrormaker/manager/core/ControllerHelixManager.java#L115

Feel free to make it configurable if you have time.

Could you please elaborate your question a bit more? We hard coded the batch size to 5 as it makes sense in production environment. Making it configurable is definitely more flexible.
