> This is a very important statement, thanks for your work Zoltan.
Thanks Penglin for taking a look.
I have a design doc about DELETE + UPDATE: 
https://docs.google.com/document/d/1GuRiJ3jjqkwINsSCKYaWwcfXHzbMrsd3WEMDOB11Xqw/edit#heading=h.5bmfhbmb4qdk

So my plan is to reuse as much as I can of this work when I'm implementing the 
UPDATE.

There will be some differences when I'll implement it for partitioned tables, 
because partition evolution introduces additional complexities. I'll update the 
design doc with the final solution once we have it implemented.
