Spark session extensions comments enhancement
Why are the changes needed?
The list of sequence given in spark session extensions seems to follow a specific order up to Planning Strategies, and the Customized Parser comes below that, this may sound a bit confusing for certain users, who are trying to modify the sql in the initial stage, they may think that before the sql hits parser there is some kind of pre-analyzer and pre-optimization happening, therefore I am requesting to add a note regarding this.
