Maybe I don't get what you are trying to do, but using Cassandra and
Hector, what I do is:
I have the following column family definition
CREATE COLUMN FAMILY CF_NAME
with comparator = 'CompositeType(LongType(reversed=true),UUIDType)'
and default_validation_class = 'UTF8Type'
and key_val
Thanks, This post helped a lot, I discovered that the built-in comparators
have a static instance called *reverseComparator.* My exact requirement was
to create an API that allows creating a Column family with the required
parameters, one such parameter was a flag that indicates the column order.

I think you can drop the compiler since that feature already exists.

Hi,
My requirements is to get retrieve column values, sorted by column names in
reverse order (column names are 'long' type). The way I am trying to
implement this is by using a custom comparator. I have written the custom
comparator by using 'org.apache.cassandra.db.marshal.BytesType' and
alterin
