I am currently working on a system with Cassandra that is written

to access the data in Cassandra (Python, C++ etc.). What is the best
way to store data to ensure I can do this? Should I serialize
everything to strings/json/xml prior to the byte conversion? We
currently use the Hector serializer, I wondered if we should just
switch this to something like Jackson/JAXB? Any thoughts very welcome.
I believe most high level (non-Thrift) clients convert types to/from
bytes consistently without additional serialization (XML, JSON, etc).
There may be a few tricks to working with TimeUUIDs for slices, but at
least the Java and Python versions appear to be compatible. It's
probably worth writing a few tests using your target languages to make sure:

Don't see a C++ client, but a quick Google search turned up:
