Eric Brewer

So, uh, CAP stands for consistency, availability, and partitioning.

It's also called Brewer theorem.

I used to work with Eric Brewer, who was a Berkeley professor, right? So, uh, basically it says out of these three, three things for distributed system, you can only optimize for two.

You cannot choose all three.

Then I find that's very, very easy way...

So it's not like there is a main thing, but...

In any case, so CAP theorem, it's actually a concept which was defined by the computer scientist Eric Brewer on a conference which is called PODC in the beginning of this century, in 2000.

And basically, this theorem states that if you have a distributed system, it can only provide two or three properties, which basically create the word CAP, like C-A-P.

And those three letters are actually properties.
