Yeah, you might want to check 1.1.5, 1.1.2 is so ancient :)

I used Pelops and now I tried Astyanax and I get no details on the value
that cassandra is analyzing - only the composite key is in the error
message. If I insert a String instead of the Long (Long.toString(...) and
Long.valueOf()) my tests work but my column size is larger of course. I can

More details would help, like at least the query you're using to do
the insertion and that fails, as well as the exact error message.

And as for the queries, I want to retrieve columns (satisfying from a list

Now this type of queries are not possible with composite columns but it is
