It's certainly possible to have a CompositeType key_validation_class. What
made you think that you cannot?

I couldn't make it work with DynamicComposite though.
I have not found any examples of utilizing a CompositeType of
DynamicCompositeType as a row key. Is doing this frowned upon? All the
examples I've seen have been using a CompositeType only for Column names
(or values).
My particular use case involves having the two components in the key being

Is this a lib I can just drop into a 0.7 instance of cassandra and use?
I'm not sure what to make of the README about not using it with versions
earlier than 0.8.0-rc1.
https://github.com/riptano/hector-composite
the goal is to start using CompositeTypes in 0.7 (which I can't upgrade
to 0.8
If your version of Cassandra does not support composite you need to
upgrade, If the server is not aware the column is composite it will not be
able to use them to full effect. You likely will not get the sorting and
slicing capabilities you want.

It was developed for 0.7x but we then made a few changes so that it
would work with 0.8-rc1 that broke the 0.7 compatibility. The idea at
the time was to do a 0.7 branch for it but it looks like that never
got checked in. If you roll back to the previous commit it should
give you a version that

Hey, is there any documentation or examples of how to use the CompositeType? I
can't find anything about it on the wiki or the datastax docs.
Cheers,

You should give a look at https://github.com/edanuff/CassandraIndexedCollections
This is a rather good starting point for Composites.

With the current implementation of CompositeType in Cassandra 0.8.1,
is it recommended practice to try to use a CompositeType as the key?
Or are both, column and key, equally well supported?
The documentation on CompositeType is light, well non-existent really, with

If you are using OPP, then you can use CompositeType on both key and
column name; otherwise(Random Partition), just use it for columns.

If you were doing composite keys anyway (common approach with time
series data for example), you would not have to write parsing and
concatenation code. Particularly useful if you had mixed types in the
key.
Exactly. In any case, I just answered my own question. If I need
range, I can just make another column family where the column name are
these keys
