Some characteristic comparisons of Message Queuing components

RabbitMQ
Based on AMQP implementations, the traditional messaging queue system is implemented based on Erlang. Veteran MQ Products. The AMQP protocol is more used in enterprise systems, with scenarios that require high data consistency, stability, and reliability, followed by performance and throughput.
Kafka
The main feature of LinkedIn's open source MQ system is the pull-based model for processing message consumption, the pursuit of high throughput, the first goal is to log collection and transfer, 0.8 start to support replication, do not support transactions, suitable for generating large amounts of data for the data collection business of Internet services.
ZeroMQ
Just a pattern library of network programming, the common form of network requests (packet management, link management, publish subscriptions, etc.) modeled, modular, in short socket, under MQ. For MQ, network transport is only a part of it, more need to deal with is the message store, routing, broker Service discovery and lookup, transaction, consumption mode (ACK, re-investment, etc.), cluster services, etc.
NSQ
The distributed real-time messaging platform based on the Go language, which can be used for real-time messaging services in large-scale systems, and capable of handling hundreds of millions of levels of messages per day, is designed to provide a robust infrastructure for decentralized services running in a distributed environment. The NSQ has a distributed, decentralized topology that features no single point of failure, fault tolerance, high availability, and the ability to guarantee reliable message delivery. The NSQ is very easy to configure and deploy, with maximum flexibility and support for many message protocols.
Redis
is a key-value NoSQL database, although it is a Key-value database storage system, it natively supports MQ features, such as the stack Overflow using the queue feature to combine push messages with websocket and update cache policies.
