This directory contains the implementation of gRPC's name resolution framework.
The name resolution framework provides a pluggable mechanism for resolving a logical name into a list of network addresses. This is a key component of gRPC's load balancing and failover systems.
resolver.h/resolver.cc: Defines the coreResolverclass, which is the main interface for name resolution.resolver_factory.h: Defines theResolverFactoryclass, which is used to createResolverinstances.resolver_registry.h/resolver_registry.cc: Defines a registry forResolverFactoryinstances.dns/: An implementation of name resolution that uses DNS.fake/: A fake implementation of name resolution for testing.google_c2p/: An implementation of name resolution that is specific to Google's C2P infrastructure.sockaddr/: An implementation of name resolution that uses a list of socket addresses.xds/: An implementation of name resolution that uses XDS.
- The name resolution framework is a key component of gRPC's networking infrastructure.
- It provides a flexible and extensible way to add new name resolution mechanisms to gRPC.
- The
Resolverinterface is designed to be simple and easy to implement, which makes it easy to add support for new name resolution mechanisms.
