ugrpc::client::ClientFactoryComponent Class Reference

#include <userver/ugrpc/client/client_factory_component.hpp>

Detailed Description

Provides a ClientFactory in the component system.

Multiple ClientFactoryComponent instances may be created if different parameters are required for different clients.

Authentication

Authentication is controlled by auth-type static config field. Possible values:

• insecure (InsecureChannelCredentials - default)
• ssl (SslCredentials)

Default (system) authentication keys are used regardless of the chosen auth-type.

Service config

As per https://github.com/grpc/grpc/blob/master/doc/service_config.md service config should be distributed via the name resolution process. We allow setting default service_config: pass desired JSON literal to default-service-config parameter

Static options:

The default component name for static config is "grpc-client-factory".

Name	Description	Default value
task-processor	the task processor for blocking channel creation	-
channel-args	a map of channel arguments, see gRPC Core docs	{}
native-log-level	min log level for the native gRPC library	'error'
auth-type	authentication method, see above	-
default-service-config	default service config, see above	-
channel-count	Number of underlying grpc::Channel objects	1
middlewares	middlewares names to use	[]
