Hey
I want to work towards the follwing feature in TODO list:
Prevent index uniqueness checks when UPDATE does not modify the
columnUniqueness
(index) checks are done when updating a column even if the column is not
modified by the UPDATE. However, HOT already short-circuits this in common
cases, so more work might not be helpful.

So I wanted to know if someone is already working on this.

Thanks
Abhinav Batra
