> Right now, when adaptive query execution is enabled, in most of cases, we will shuffle input tables for every join. However, once we finish our work of https://issues.apache.org/jira/browse/SPARK-10665, we will be able to have a global on the input datasets of a stage. Then, we should be able to add exchange coordinators after we get the entire physical plan (after the phase that we add Exchanges).
> I will try to fill in more information later.
