This includes a mysql-connector-java 8+ query interceptor that will report to Zipkin how long each query takes, along with relevant tags like the query.
To use it, append ?queryInterceptors=brave.mysql8.TracingQueryInterceptor
to the end of the connection url.
It is also recommended to add the exception interceptor so errors are added to the span, e.g.,
?queryInterceptors=brave.mysql8.TracingQueryInterceptor&exceptionInterceptors=brave.mysql8.TracingExceptionInterceptor
By default the service name corresponding to your database uses the format
mysql-${database}, but you can append another property zipkinServiceName to customise it.
?queryInterceptors=brave.mysql8.TracingQueryInterceptor&exceptionInterceptors=brave.mysql8.TracingExceptionInterceptor&zipkinServiceName=myDatabaseService
The current tracing component is used at runtime. Until you have
instantiated brave.Tracing, no traces will appear.
