OTLP Partial success experimentation

This repo contains sample apps that simulates the behavior of OTLP exporters using old/new protos talking to servers that also use old/new protos.

Made as part of open-telemetry/opentelemetry-specification#2454 in order to ensure backwards compatibility.

There's 2 servers - one returning the current "old" protos, without the partial success fields and the other returning the "new" protos, containing the new fields to be used for partial success export requests.

And there's 2 clients - one using the current "old" protos, talking to the server that returns the new protos. The other client uses the new protos and talks to the server using the "new" protos.

The clients can be changed to talk to the other servers.

The client using the new protos logs the new fields to the console when they are available.

How to run

Start both servers:

dotnet run --project ./src/OldServer/OldServer.csproj
dotnet run --project ./src/NewServer/NewServer.csproj

Then run each client

dotnet run --project ./src/OldClient/OldClient.csproj
dotnet run --project ./src/NewClient/NewClient.csproj

Requirements

  • .NET SDK 6.x
