I wonder if Oracle’s secret to performance is just that they redefined what “safe” means to be less so.
Maybe, but that’s basically the definition of FUD.
I don’t think it’s FUD. It’s pretty uncontested that they what they call Serialisable isn’t.
Whether that contributes significantly to their performance is uncertain but not in a way that engenders fear.
I may have missed something but I didn’t see anything in the article about that.
You’re probably speaking from a position of knowledge (certainly relative to me); a link to something explaining when/how oracle is unsafe would be enough to make it not-fud.
Read the first paragraph under the heading “Isolation in Real Databases” carefully.
Ahh - the mention of four different systems there got me thinking it was a widespread thing, but on closer inspection I see that the other three have all avoided or moved away from the misleading name. Thanks for pointing that out.
