Re: Analysis: INSERT ON DUPLICATE UPDATE VS UPDATE
I am trying to understand that amount of work...
What operations are really required to do each of them so the different is that big.
I am not a DB developer and the development team (with multiple years of experience developing SP) cannot tell me the reason.
I could go to the source code of MYSQL and spend lots of time there but I might get lost...
And this is the original reason of my question. What is soo expensive it can take up to 2 times in NDB...
