> DataTracker has become a bit of a quagmire, and not at all obvious to interface with, with many subtly different modifiers. I suspect it is still subtly broken, especially around error recovery.
> I propose piggy-backing on CASSANDRA-7705 to offer RAII (and GC-enforced, for those situations where a try/finally block isn't possible) objects that have transactional behaviour, and with few simple declarative methods that can be composed simply to provide all of the functionality we currently need.
> See CASSANDRA-8399 for context
