Context Propagation Between Python And Java

This project is a learning example for context propagation between Python and Java.

introduction

This Project demonstrates the Context Propagation capability of OpenTelemetry (OTel) between Python and Java service. Project is divided into two parts: gRPC and HTTP -- designed to show the differ between two protocols. Each part contains subdirectories which contain the Java/Python code respectively. The grpc directory also contains the .proto file. Further infomation please look into grpc's or http's README.md file and the Explanatory.md.
