Hi Easwar,

Thanks for the reply. Sorry I should be clear that I am using the grpc c++
client.

use the LDS/RDS/CDS.
Yes.  But the grpc client first issues a LDS request and waits for 15s
timeout before sending eDS request. my question is is there a way around
this 15s timeout?
I thought for a bit it's hard to tell if the endpoint does not implement
LDS or it's just very slow. Unless these are some options I missed in the
service config or xDS bootstrap file.

In the end, I found it's easier to implement LDS, CDS.

Best,
yishu
