ZeroMQ - Features

ZeroMQis also known as 0MQ, or ZMQ. It is a lightweight open-source messaging library, which provides a simple and organized way to implement messaging patterns in both web and mobile applications. Here, is the some of its key features −

Messaging Pattern

ZeroMQ has several messaging patterns including −

• Request-Response: It allows a client to send a request to the server and receive a response.
• Publish-Subscribe: It allows a publisher to send messages to multiple subscribers.
• Push-Pull: It allows a producer to push messages to multiple consumers.
• Pub-Sub with filtering: It allows subscribers to filter messages based on topic.

Socket Type

ZeroMQ has several socket type including:

• REQ: It is used to request a message pattern.
• REP: It is used to response a message pattern.
• PUB: It is used to publish a message pattern.
• SUB: It is used to subscriber a message pattern.
• PUSH: It is used to push a message pattern.
• PULL: It is also used to push a message pattern.
• PAIR: It is used to bidirectional communication between two peers.
• ROUTER: It is used to routing messages between multiple peers.
• DEALER: It is used to load balancing and routing messages between multiple peers.

Key Features

ZeroMQ has several key features including:

• Asynchronous I/O: To handle multiple connections simultaneously ZeroMQ uses asynchronous I/O.
• Message Queue: To handle messages that cannot be processed immediately ZeroMQ provides a message queue.
• High Performance: Due to its high performance ZeroMQ can handle thousands of messages per second because.
• Scalability: ZeroMQ is designed to scale horizontally so that it can handle a large number of connections.
• Multi Transport: ZeroMQ supports multiple transport protocols including TCP, UDP, and in-process.
• Multi Language: ZeroMQ has bindings for many languages including C, C++, Java, Python, etc.

Use Cases

We can use ZeroMQ in financial applications, distributed systems, or real-time data streams, irrespective of the field ZeroMQ offers performance and simplicity for even the complex messaging scenarios. Following is a list of the common usages of ZeroMQ −

• Real-time System: ZeroMQ requires low latency and high throughput messaging so that it is used in real-time systems.
• Distributed System: ZeroMQ requires communication between multiple nodes so that it is used in distributed systems.
• Cloud Computing: To provide scalable and fault-tolerance messaging ZeroMQ is used in Cloud computing.
• Big Data: To provide high-performance and scalable messaging ZeroMQ is used in Big Data processing.
