Yin Huai created SPARK-11471:
--------------------------------
Summary: Improve the way that we plan shuffled join
Key: SPARK-11471
URL: https://issues.apache.org/jira/browse/SPARK-11471
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Yin Huai
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.
