Ed Anuff commented on CASSANDRA-2231:
-------------------------------------

Am I correct in that the v3 rebased to .8 doesn't include the decompose() 
methods?  I had to add those to get the v3 patch to build.  Once I did that, it 
passed the unit tests.

> CompositeType is a custom comparer that makes it possible to create 
> comparable composite values out of the basic types that Cassandra currently 
> supports, such as Long, UUID, etc.  This is very useful in both the creation 
> of custom inverted indexes using columns in a skinny row, where each column 
> name is a composite value, and also when using Cassandra's built-in secondary 
> index support, where it can be used to encode the values in the columns that 
> Cassandra indexes.  One scenario for the usage of these is documented here: 
> http://www.anuff.com/2010/07/secondary-indexes-in-cassandra.html.  Source for 
> contribution is attached and has been previously maintained on github here:
