From documentation:
Another important property of the query execution architecture is that it is dynamic, which means that the query plan may be modified while a query is in flight. Stages that are introduced while a query is running are often used to improve data distribution throughout query workers. In query plans where this occurs, these are typically labeled as Repartition stages.
