How to retrieve traces via grpc

[m1-s]

I am exploring the grpc API:

$ grpcurl -plaintext localhost:16685 list
                                        
grpc.health.v1.Health
grpc.reflection.v1alpha.ServerReflection
jaeger.api_v2.QueryService
jaeger.api_v2.metrics.MetricsQueryService
jaeger.api_v3.QueryService

Next I want to explore functions of the QueryService but receive error:

$ grpcurl -plaintext localhost:16685 list jaeger.api_v3.QueryService

Failed to list methods for service "jaeger.api_v3.QueryService": Symbol not found: jaeger.api_v3.QueryService

This is a documented issue with the reflection API: https://www.jaegertracing.io/docs/1.44/apis/

Cf #3417

how are we supposed to query traces ?

you can implement a grpc client using the schema we provide, just like you'd do with any other grpc service.
