It’s the End of the World As We Know It (NoSQL Edition)

I think Michael Stonebraker overshot the target In a 2007 paper titled, “The End of an Architectural Era”. Why is this The End?

Hence, they are 25 years old legacy code lines that should be retired in favor of a collection of ‘from scratch’ specialized engined”.

Beware the /var/tmp/.oracle Hidden Directory!

A few months ago, we had a test instance complaining that it couldn’t write to ASM.
