golang grpc: question about balancer

[zel...@gmail.com]

Hi folks,

A quick question about Go GRPC: if a balancer returns an address that it desires a connection to, and GRPC cannot connect to that address, how does the balancer get notified? Does GRPC call Up() and then down() for that connection?

In other words, as a balancer, how do I tell the difference between an address that is simply waiting to connect and one that has been failing to connect for some time: do I need to keep track of the time delta between when the Notify channel asks for the address to be connected and when Up() is called?

Thanks,

Zellyn
