Summary: OpenTelemetry Context Propgation
Key: IMPALA-14752
URL: https://issues.apache.org/jira/browse/IMPALA-14752
Project: IMPALA
Issue Type: New Feature
Affects Versions: Impala 4.5.0
Reporter: Jason Fehr
When using the hs2-http protocol, if clients pass in the OpenTelemetry context
propagation http header, then Impala must set the query's trace id and the
parent span id of the root span based on the value of this header.
General details about context propagation can be found at
https://opentelemetry.io/docs/concepts/context-propagation/
Specific details about how the OpenTelemetry C++ SDK implements context
propagation can be found at
https://opentelemetry.io/docs/languages/cpp/instrumentation/#context-propagation
with an example in the [SDK
docs](https://github.com/open-telemetry/opentelemetry-cpp/blob/75b8a2f51964df8b0f287851b36309f56d288fab/examples/http/server.cc#L52-L73).
