Not just client API's but documentation as well.  When I was a new
user, yeah the different terminology was a bit off-putting, but it was
consistent and it didn't take long to realize a CF was like a SQL
table, etc.  Honestly, I think using the same terms as a RDBMS does
makes users think they're exactly the same thing and have the same
properties... which is close enough in some cases, but dangerous in

That said, while I found the first edition informative, I found the
java/hector code examples hard to read.  Part of that was because I
don't know Java (I know enough other languages that I can follow
along) and part of that is that Java is so verbose that it just
doesn't "fit" on the printed page.  I think CQL lends itself to making
the book more readable to a wider audience, but I think there should
be a chapter on Hector/pycassa/etc.  Of course, you still need to
write code around it, and if that's Java I'm not sure how much it
