I don't see anything inherently wrong with your proposal, it would almost
definitely be beneficial in certain scenarios. We use what could be called
"static compression" (golomb-esque encodings) for some data types on our
Cassandra clusters. It's useful for representing things like full precision
d
There is a lot of overhead in the serialized data itself (just have a look at a
sstable file).
It would be great to be able to compress at the byte array level rather than
string.

Is the partitioner the only code that does comparisons on the keys of a column
family? What about get_range_slices(), does it only use the partitioner's
comparison method?

In Cassandra, strings are stored as UTF-8. In arithmetic coding compression,
the modeling is separate from the coding. A standard arrangement is to have a
0-order model, frequencies of individual bytes, 1-order model, frequencies of
two byte occurrences, and 2-order models, frequencies of three

I propose a simple idea for compression using a compressed string datatype.
The compressed string datatype could be implemented for column family keys by
creating a compressed string ordered partitioner. The compressed string ordered
partitioner works by decompressing the string and then applyi
