- class aws_cdk.aws_appmesh.DnsResponseType(value)
Enum of DNS service discovery response type.
# A Virtual Node with a gRPC listener with a connection pool set # mesh: appmesh.Mesh node = appmesh.VirtualNode(self, "node", mesh=mesh, # DNS service discovery can optionally specify the DNS response type as either LOAD_BALANCER or ENDPOINTS. # LOAD_BALANCER means that the DNS resolver returns a loadbalanced set of endpoints, # whereas ENDPOINTS means that the DNS resolver is returning all the endpoints. # By default, the response type is assumed to be LOAD_BALANCER service_discovery=appmesh.ServiceDiscovery.dns("node", appmesh.DnsResponseType.ENDPOINTS), listeners=[appmesh.VirtualNodeListener.http( port=80, connection_pool=appmesh.HttpConnectionPool( max_connections=100, max_pending_requests=10 ) )] ) # A Virtual Gateway with a gRPC listener with a connection pool set gateway = appmesh.VirtualGateway(self, "gateway", mesh=mesh, listeners=[appmesh.VirtualGatewayListener.grpc( port=8080, connection_pool=appmesh.GrpcConnectionPool( max_requests=10 ) )], virtual_gateway_name="gateway" )
DNS resolver is returning all the endpoints.
This also means that if an endpoint is missing, it would drain the current connections to the missing endpoint.
DNS resolver returns a loadbalanced set of endpoints and the traffic would be sent to the given endpoints.
It would not drain existing connections to other endpoints that are not part of this list.
