public interface ChannelEndpoint
Represents a Spanner server endpoint for location-aware routing.
Each instance wraps a gRPC ManagedChannel connected to a specific Spanner server. The
ChannelEndpointCache creates and caches these instances.
Implementations must be thread-safe as instances may be shared across multiple concurrent
operations.
