ZMQ (hereinafter referred to as ZeroMQ) is a simple and easy-to-use transport layer, a socket library like a framework, which makes Socket programming simpler, more concise and more performant. Is a message processing queue library that elastically scales across multiple threads, cores, and host boxes. The clear goal of ZMQ is to "become part of the standard network protocol stack and then enter the Linux kernel.
Feature introduction:
ZMQ is not like a message queue server in the traditional sense. In fact, it is not a server at all. It is more like It is a bottom-level network communication library, which is encapsulated on top of the Socket API and abstracts network communication, process communication and thread communication into a unified API interface

Disadvantages:
zeroMq does not support message persistence and is prone to data loss.

Supports 3 modes:
1. Hello world
Single queue mode
2. Publish-subscribe
Subscription mode
3. PipeLine model
If we need to count the logs of each machine, we need to distribute the statistical tasks to each node machine , finally collect the statistical results and make a summary
