anuraaga commented on issue #609: Don't make spans for comments or SET statements in SQL URL: https://github.com/apache/incubator-zipkin-brave/issues/609#issuecomment-492227331 A few observations - `/*` should never be the name of a span. I suspect the MySQL instrumentation needs to be updated to handle this more sanely. FWIW, I don't think I've ever seen this I wonder if there is a connector option pretending that comment - Traces of background spans like `SET` and health check have always been annoying. I'm only interested in tracing queries in the context of a request (if you know what I mean ;) so HikariCP's background queries are boring. - Unfortunately it's not as simple as filtering the span name by itself. Select used in health check I don't need but select used by the app I do. It's not clear to me whether decoration etc have the flexibility for this sort of filtering. Though I don't know if an interceptor option does either - it's really a pain that MySQL connector doesn't use the perfectly good service loader mechanism for extension... I think we'd need to play around to see what ends up cleanest. But definitely want to help getting rid of junk MySQL spans from my apps!
