Hi Dean,

Thanks for the feedback.

OK so as I suspected, my actual description of the data which is going
to be stored in Cassandra and of course the use cases the data will be
subject to were not described as verbosely as is required to get more
substantial feedback. The reason I didn't go into more fine grained
detail regarding typical requirements for cf's, c's and sc's is that
webpage data can change quite substantially between pages, hosts, etc.

Some context here. We recently introduced a whole series of new
serializer options in Apache Gora gora-cassandra module 0.2.1 [0]
however I seem to be having problems populating Cassandra with certain
super column fields when mapping from webpages to super columns. I'm
trying to determine if each field (for the webpage --> cassandra
mapping) is correctly configured to store and retrieve the data
efficiently.

Thanks for your comments, I'll go away and have a more thorough think
+ test various configs in an attempt to find a best option.

Thanks

Lewis
