如何在C ++ GRPC客户端中创建到一个特定地址的多个连接

Question

I wrote a c++ grpc client, and wanted to create multiple connection by create multiple channel, just like the hello world example .

But only one connection for the specific address was created. So how to create multiple connection to the server?

Answer 1

Honestly, I don't see significant reasons for that (at least for basic use cases). You don't need to create multiple connections to have some kind of connection pooling (as you might want to do while connecting to RDBMS like PostgreSQL). The bandwidth of physical transport (TCP connection) will be fully utilized by the single network connection.
