Efficient and easy-to-use Python communication library: Pynng, achieving high concurrency and low latency communication

Estimated read time 3 min read

In today’s fast-paced software development world, asynchronous programming is getting more and more attention. The traditional synchronous programming model can no longer meet the requirements of high concurrency and low latency. Nanomsg Next Generation (nng), as an emerging asynchronous messaging library, provides high-performance, low-latency communication solutions. Pynng is the representative of nng in the Python world, allowing Python developers to experience the charm of asynchronous programming.

Introduction to Pynng

Pynng is a third-party package for Python that encapsulates the functions of nng and provides a Python-friendly API. Through Pynng, developers can use the powerful functions of nng in Python code without delving into the C language implementation details of nng. It supports all mainstream operating systems, is easy to install and simple to use.

Asynchronous network model

The core of Pynng lies in its asynchronous network model. Different from traditional synchronous Socket programming, Pynng is based on the event loop mechanism and can efficiently handle a large number of concurrent connections and avoid thread blocking. Developers only need to focus on sending and receiving messages, and the underlying network communication is automatically handled by Pynng.

message pattern

The message mode is one of the highlights of Pynng. It supports a variety of classic messaging modes, such as request-response mode, publish-subscribe mode, pipeline mode, etc. Each mode has its specific usage scenarios. Developers can choose the appropriate mode according to their needs and easily build distributed systems.

secure transmission

In some scenarios, message security is crucial. Pynng has built-in multiple secure transmission protocols, such as TLS, ZeroTCP, etc., to ensure the confidentiality and integrity of data during transmission. Developers can obtain stable and reliable secure communication capabilities without repeatedly “reinventing the wheel”.

Performance optimization

High performance is one of Pynng’s main features. The underlying nng library is written in C language and has extremely high operating efficiency. At the same time, Pynng also provides optimization methods such as message queues and zero-copy to minimize system overhead and achieve low-latency, high-throughput communication.

Application scenarios

Pynng can be widely used in various fields, such as Internet of Things, microservices, games, finance, etc. Whether you are building a high-real-time sensor network or developing high-concurrency online services, Pynng is the best choice.


In short, Pynng has brought a new trend of asynchronous programming to the Python world. It is simple, efficient, safe and flexible, and solves the performance bottleneck problem that Python developers have encountered for a long time. I believe that through Pynng, Python developers will sail in the ocean of asynchronous programming and create a broader application space.
