Field Detail

TOKEN_METADATA_KEY

public static final io.grpc.Metadata.Key<String> TOKEN_METADATA_KEY

The opaque token given by the remote balancer for each returned server address. The client will send this token with any requests sent to the associated server.

ATTR_LB_ADDR_AUTHORITY

@EquivalentAddressGroup.Attr
public static final io.grpc.Attributes.Key<String> ATTR_LB_ADDR_AUTHORITY

The naming authority of a gRPC LB server address. It is an address-group-level attribute, present when the address group is a LoadBalancer.

ATTR_LB_PROVIDED_BACKEND

@EquivalentAddressGroup.Attr
public static final io.grpc.Attributes.Key<Boolean> ATTR_LB_PROVIDED_BACKEND

Whether this EquivalentAddressGroup was provided by a GRPCLB server. It would be rare for this value to be false; generally it would be better to not have the key present at all.
