--------------------------------------

             Summary: Push notification when tracing completes for an operation
                 Key: CASSANDRA-7807
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7807
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Tyler Hobbs
            Priority: Minor
             Fix For: 3.0


Tracing is an asynchronous operation, and drivers currently poll to determine when the trace
is complete (in a loop with sleeps).  Instead, the server could push a notification to the
driver when the trace completes.

I'm guessing that most of the work for this will be around pushing notifications to a single
connection instead of all connections that have registered listeners for a particular event
type.
