How to use it
Tracer with ScopedSpan
Previously,
val span = Tracing.currentTracer().startScopedSpan()
try {
// whatever you want to do to trace with span
} finally {
span.finish()
}
Now we can do like this
val result = tracer.scopedSpan("DB ACCESS") {
// whatever you want to do to trace with span
}You can pass start timestamp, too
tracer.scopedSpan("DB ACCESS", startTimestamp) {
// whatever you want to do to trace with span
}Span
Previously,
span.start()
try {
// whatever you want to do to trace with span
} finally {
span.finish()
}
Now we can do like this
span.use {
// whatever you want to do to trace with span
}You can pass start timestamp, too
span.use(startTimestamp) {
// whatever you want to do to trace with span
