@wujianping10043419 this change is too trivial to merge, I am sorry. The main reason for not merging is because this will mess up the git blame for the given code, which is sometimes very useful to find out why we implemented something the way it is. Can you close this? Thank you for your contribution. |

org.apache.spark.sql.execution.exchange.ShuffleExchangeExec:
There is a nested "if or else" branch within the "needtocopyobjectsbeforguffle()" function.
The <sortBasedShufffleOn> condition in the first layer "if" has the same value as the <bypassIsSupported> condition in the second layer "if", that is, <bypassIsSupported> must be true when <sortBasedShufffleOn> is true.
In addition, the <byPassMergeThreshold> condition will be used in the second layer "if" and should not be calculated until needed.
It's to remove the <bypassIsSupported> condition in the second layer " if" and to move the <bypassmergethreshold> calculation backward
