Thanks Petrov I will read what you sent a link to. I am trying to find out what capability CQL wise is truely available in order to determine my end state for my data model.
Last night after I discovered the cashing issues that affected queries I was able to create two queries one to get a list of ids then from that built up the IN list for the second query to get detail data from a master column family. Prevously in SQL Server I would use one query using IN and nested select. Hopefully tonight I will be able to compare the performance of the two.

Hi Tony, you can check out a guide here: which explains pretty most of things you need to know about queries for starters. 

It includes CQL code examples, just disregard Clojure ones, there's nothing strictly Clojure-driver specific in that guide.

You can use the actual item_ids however, 

Select * from items Where item_id IN (1, 2, 3, ..., n)

CQL does not support sub-queries.

Hi All,
I am using the DataStax driver and got prepared to work. When I tried to use the "IN" keyword with a SQL it did not work. According to DataStax IN should work.
So if I tried:
Select * from items Where item_id IN (Select item_id FROM users where user_id = ?)
Thanks for the feedback.
