can already calculate an MD5 after all.
First of all thank you very much for your contribution in data pipeline
ecosystem, your projects are super nice and I'm very happy and glad
contributing
Second, to add more explanation for my long first message, my request is
super simple:
If you do upsert and the destination table contain a hash column , we should
add a check box that says "update only modified column" and give the
destination hash column name
and instead of comparing all columns and then decided whenever to update or
not, we update only the ones with modified hash. We drastically improve upsert
time . And this is a common best practice among dev. But it take much time to
do it manually. You can take a look to my screen capture
I'll be happy to exchange more if you want
