Go - IDLE_TIMEOUT support

[Amit Saha]

The connectivity semantics documentation [1] states that a connection
will move from READY to IDLE if no active requests have been made for
IDLE_TIMEOUT duration.
However, in Go, i don't see such a configuration, is this state used
in Go grpc implementation or is this being implemented? [2]

Thanks,
Amit

I don't believe we have this logic about the state change to IDLE after a certain time of not sending RPC's to connection. Forwarding this to my teammate who has been here much longer and can answer this question better.

IDLE_TIMEOUT isn't supported in go. It's tracked in https://github.com/grpc/grpc-go/issues/1719

The PR you mentioned is a step towards this goal.

But that only covers connection idleness, not at the ClientConn level (e.g. it doesn't turn down resolver and balancers)

Thank you Zach and Menghan.
