gRPC Persistent Connections??

[Lokanadham M]

If gRPC connections are persistent, a single client will always talk to a single backend in that configuration. It's fine if you have lots of clients but how load balancing is done?

How server is able to handle so many open connections?? Won't it hit open file discriptors limit??

Can some one please explain how it was implemented at socket level to handle that many connections??

With what programming language(s) are you working with gRPC? It's likely that the details of the answers to your questions will vary from one programming language to another.

Sometimes load balancing is done in the client by representing as one connection to the application what are actually several connections on the wire to several different servers. Sometimes load balancing is done but putting a running a load balancer on a host between clients and servers.

I suspect that the answers to these questions are implementation-dependent.
