Chapter 1 - Memory and Persistence: Typo?

[Andreas Arnold]

In chapter 1, Memory and Persistence, first paragraph you write

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only a 9 keys has changed"

Did you mean

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only a key has changed"

or

" By default, Redis will save the database every 60 seconds if 1000 or more keys have changed all the way to 15 minutes if only 9 keys have changed"?

[Karl Seguin]

Fixed with "all the way to 15 minutes if 9 or less keys has changed".

Cheers!
