The latest revision of Architecting for Scale has become very large:
An mobi with 20 MB? A PDF with 11 MB? Are you out of your minds?
This is a technical book, not an artbook.
Please shrink these files to manageable sizes.
And please check your workflows - why was this not catched in QA?
The same happened with the latest revision of the Cassandra book - there the files are even larger.
