GRPC Call blockingUnaryCall

Hi all,

making a client-server call using the following method to open the channel:

ManagedChannelBuilder.ForTarget (<hostname>: port) takes 15 seconds to get the response. Where hostname is the container name 

Can you explain to me what it depends on?

Thanks-

It typically does a DNS resolution, connects to the addresses one-by-one until it finds one that works, does a TLS handshake, and the RPC exchange which includes the server's only latency. 15 seconds is a long time. I'd either expect the server is slow to respond or the networking is poor (e.g., dropped packets) causing lots of latency.

Can you help me?

What are you accomplishing via the NameResolverFactory? The deprecation notice and the linked issue provide some guidance. But if you share your specific use case I can point you to the replacement approach.
