> It can be possible to use an external tracing solution in Cassandra by abstracting out the writing of tracing to system_traces tables in the tracing package to separate implementation classes and leaving abstract classes in place that define the interface and behaviour otherwise of C* tracing.
> Then via a system property "cassandra.custom_tracing_class" the Tracing class implementation could be swapped out with something third party.
> An example of this is adding Zipkin tracing into Cassandra in the Summit [presentation|http://thelastpickle.com/files/2015-09-24-using-zipkin-for-full-stack-tracing-including-cassandra/presentation/tlp-reveal.js/tlp-cassandra-zipkin.html]. Code for the implemented Zipkin plugin can be found at https://github.com/thelastpickle/cassandra-zipkin-tracing/
> In addition this patch passes the custom payload through into the tracing session allowing a third party tracing solution like Zipkin to do full-stack tracing from clients through and into Cassandra.
