what is the difference between zipkin v1 with v2?

[keets2012]

hello. I'm building micro-service in go. I found several go clients, such as zipkin-go and zipkin-go-opentracing while zipkin-go-opentracing supports v1,zipkin-go supports v2.

i wanna know the difference between zipkin v1 with v2.

The format is different. Zipkin V1 is and old (on deprecation) much more verbose and requieres more data whereas zipkin v2 is the new, simple and concise. While zipkin-go-opentracing is supporting only v1 ATM, there is an ongoing effort to move it into v2 (which will be finished in the upcoming weeks, see openzipkin-contrib/zipkin-go-opentracing#123). We highly recommend to avoid v1 clients if possible. BTW, for further questions like this join us on gitter: https://gitter.im/openzipkin/zipkin

ok, got it. Hope to see that zipkin-go-opentracing supports for zipkin v2.
