Benedict commented on CASSANDRA-8568:
-------------------------------------

Improvements to Byteman testing can be a follow up ticket, which I'll get to in 
a week or two. It's ready for review as stands, although I would prefer 
CASSANDRA-8984 take priority.

> Impose new API on data tracker modifications that makes correct usage obvious 
> and imposes safety

> 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
