Interface GrpcSender

public interface GrpcSender

An abstraction for executing gRPC calls, allowing for implementations backed by different client libraries.

While this interface is public, implementing a custom sender is generally not recommended. The opentelemetry-java project provides built-in implementations that cover virtually all cases.

Since:

1.59.0
