This includes a tracing event listener for P6Spy (a proxy for calls to your JDBC driver). It reports to Zipkin how long each statement takes, along with relevant tags like the query.
P6Spy requires a spy.properties in your application classpath
(ex src/main/resources). brave.p6spy.TracingP6Factory must be in the
modulelist to enable tracing.
modulelist=brave.p6spy.TracingP6Factory
url=jdbc:p6spy:derby:memory:p6spy;create=true
By default the service name corresponding to your database is the name
of the database, but you can add another property to spy.properties
named zipkinServiceName to customise it.
The current tracing component is used at runtime. Until you have
instantiated brave.Tracing, no traces will appear.
