> Hi,
> I have come across the use case where some of the incoming events have same timestamps for the insert and update event. In this case I want to depend on the other field for ordering. In simple terms, if the primary sort ties, i want to do secondary sort based on other field, if that too ties, go to the other field etc.,. it would be good if hudi has this functionality.
