Who is using ZeroMQ?

Who uses ZeroMQ? 54 companies reportedly use ZeroMQ in their tech stacks, including Alibaba Travels, energy2market, and XING.

What does ZeroMQ stand for?

asynchronous messaging library
ZeroMQ (also spelled ØMQ, 0MQ or ZMQ) is an asynchronous messaging library, aimed at use in distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ZeroMQ system can run without a dedicated message broker. The library’s API is designed to resemble Berkeley sockets.

What is ZeroMQ socket?

ZeroMQ (also known as ØMQ, 0MQ, or zmq) looks like an embeddable networking library but acts like a concurrency framework. It gives you sockets that carry atomic messages across various transports like in-process, inter-process, TCP, and multicast.

What is ZeroMQ good for?

ZeroMQ is a library used to implement messaging and communication systems between applications and processes – fast and asynchronously.

Why ZeroMQ is fast?

ZeroMQ provides several transport protocols: inproc, IPC, TCP, TIPC and multicast. For connecting two processes in the same server it is considered that IPC is the fastest option, thanks to the usage of Unix Domain Sockets, thus achieving very low latency.

Is ZeroMQ persistent?

As far as I know, Zeromq does not have any persistence. It is out of scope for it and needs to be handled by the end user. Just like serializing the message.

What is difference between ZeroMQ and RabbitMQ?

Difference Between ZeroMQ vs RabbitMQ. ZeroMQ is an open-source, high-performance messaging library. It is cross-platform and supports cross languages, and is light-weight and fast. RabbitMQ is a traditional message broker with a variety of message protocols being implemented.

Does ZeroMQ use sockets?

Sockets are the de facto standard API for network programming. That’s why ZeroMQ presents a familiar socket-based API. One thing that make ZeroMQ especially tasty to developers is that it uses different socket types to implement any arbitrary messaging pattern.

Does ZeroMQ support MQTT?

ZeroMQ is a flexible toolkit for writing different communications patterns, whereas MQTT is broker-based publisher/subscriber system. Although 0MQ has pub/sub sockets as one of it’s many patterns, the wire format is different than that used by MQTT, so they are certainly not directly compatible.

Does MQTT guarantee delivery?

There is no guarantee of delivery. The recipient does not acknowledge receipt of the message and the message is not stored and re-transmitted by the sender. QoS level 0 is often called “fire and forget” and provides the same guarantee as the underlying TCP protocol.

Which is better ActiveMQ or RabbitMQ?

RabbitMQ is the best performance wise according to me, but it does not have failover and recovery options. ActiveMQ has the most features, but is slower. Update : HornetQ is also an option you can look into, it is JMS Complaint, a better option than ActiveMQ if you are looking for a JMS based solution.
