What is the use of Traceparent in the header? #1570

Closed xiaolipro closed 1 month ago

xiaolipro commented 1 month ago

I want to know what the "tracepoint" in the "Header" is for and when it was set. I looked through the source code and didn't find out when it was assigned a value. 我想知道Header中的tracepoint是用于什么目的，何时赋值的。我查看了源代码，没有发现它被赋值，只找消费者从header中解析的逻辑，他在哪里被赋值呢？我希望伪造一份header以便仍然在使用cap的消费者无缝兼容 image

Traceparent is for OpenTelemetry trace contexts, just cap-msg-id and cap-msg-name are required when processing event for external systems.
