Managing managed channels

[Mahesh Lal]

Hi

We are using an approach in which we create a gRPC client with a channel, make a single call with it and then close the connection. This gets done for every request that needs to be made to the systems.

Does anyone see any issues with this? Is it efficient? What's the most accepted practice?

Thanks.

It is not efficient.

In the future we *might* be able to optimize this away a little, but it's always going to be strictly better to keep channels around long term.

Most applications will want to create their stubs at initialization time and destroy them at shutdown.
