  name: Jaeger Collector API
  description: The Jaeger Collector API receives trace spans from instrumented applications and SDKs. Since Jaeger v1.11 the
    primary protocol is the jaeger.api_v2.CollectorService gRPC endpoint; the collector also accepts OTLP traces (binary gRPC,
    Protobuf over HTTP, JSON over HTTP) since v1.35, as well as legacy Thrift over UDP and HTTP formats.

  name: Jaeger Remote Storage API
  description: The Jaeger Remote Storage API is a gRPC-based interface that allows extending Jaeger with custom storage backends.
    Any backend implementing this API can be deployed as a remote gRPC server and plugged into Jaeger components in place
    of built-in storage engines (available since v1.30).

    for distributed trace collection. It is implemented by the jaeger-collector and defined in the sampling.proto IDL, supporting
    both static file-based and adaptive sampling strategies.
