Perhaps you could just store the objects as a simple key-value

index the components of the key (presumably in another table), using

On the other hand, shuffling requires moving tokens around the

It doesn't ring a bell; For something like this, it would be great to
have a ticket with details on your environment, steps to reproduce,
the full output of the logs, and where possible, the data.

I read that as advice to reexamine your data model so that queries are
performed on rows (slices), and not for them (range queries).

My guess would be that, total number of rows in the columnfamily
notwithstanding, there are only 79 for the given the predicates.

While it's meant more as a language specification than a guide,

Unfortunately, Cassandra is documented about as well as most
open-source projects. :(
or = blob) will allow you
have all column names as bytes, and likewise, default_validation =
blob will make bytes the default for column values.
If you want to create schema for specific columns that have binary
