> The select operator's optraits logic as stated in the comment is,
> // For bucket columns
> // If all the columns match to the parent, put them in the bucket cols
> // else, add empty list.
> // For sort columns
> // Keep the subset of all the columns as long as order is maintained.
> However, this is not happening due to a bug. The bool found is never reset, so if a single
match is found, the value remains true and allows the optraits get populated with partial
list of columns for bucket col which is incorrect.
> This may lead to creation of SMB join which should not happen.
