Working with UNIX Domain Sockets
Explore creating concurrent UNIX domain socket servers in Go to handle multiple client connections efficiently. Understand how UNIX sockets provide faster, resource-efficient IPC compared to TCP/IP, and learn to implement echo servers with goroutines and file-based socket handling.
We'll cover the following...
A UNIX Domain Socket or inter-process communication (IPC) socket is a data communications endpoint that allows us to exchange data between processes that run on the same machine. We might ask, why use UNIX domain sockets instead of TCP/IP connections for processes that exchange data on the same machine? First, because UNIX domain sockets are faster than TCP/IP connections, and second, because UNIX domain sockets require fewer resources than TCP/IP connections. So, we can use UNIX domain sockets when both the clients and the server are on the same machine.
