This article mainly explains "how to select java message middleware". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to select java message middleware".

With so many technologies, how to select the model?

First of all, for Ali's RocketMQ, because it is Ali open source, for the domestic open source to maintain a cautious attitude, temporarily do not take the middleware.

So we can only choose one of ActiveMQ, RabbitMQ, ZeroMQ, Kafka as message queuing middleware.

Let's compare it from several dimensions.

1. Community activity

From the current online information, RabbitMQ, activeMQ, ZeroMQ among the three RabbitMQ is absolutely the first choice.

2. Message persistence

ZeroMq does not support message persistence, both ActiveMQ and RabbitMQ support.

3. Core technology

Reliability, flexible routing, clustering, transactions, highly available queues, message sorting, problem tracking, visual management tools, plug-in systems, and so on.

RabbitMq / Kafka is the best, ActiveMQ is the second, and ZeroMQ is the worst. Of course, ZeroMQ can also do this, but you have to write code to implement it manually, which is a lot of work. Especially in reliability: persistence, delivery confirmation, publisher confirmation, and high availability.

4. High concurrency

There is no doubt that RabbitMQ is the highest, because RabbitMQ is implemented by the Erlang language, which is born with high concurrency and high availability.

The above comparison of the reference source network is more or less the same. To sum up, you need to choose between RabbitMQ and Kafka that suits you. There is no doubt that RabbitMQ and Kafka are also two kinds of message queue middleware on the market, which can be seen from the network materials and interview requirements.

How to choose?

Generally speaking, distributed message middleware Kafka and RabbitMQ have their own characteristics in industry recognition, service support, reliability, maintainability, compatibility, ease of use and so on. Kafka is better than RabbitMQ,Kafka in open source license, product activity, performance, security, scalability and other aspects. The license is looser, the activity is higher, the performance is much higher than RabbitMQ, and it can provide better protection in terms of security and scalability. Kafka is only slightly less functional than RabbitMQ, but it already has the main functionality.

Combining all the above evaluation results, we decided to choose Kafka.

After the study of this article, I believe you have a deeper understanding of how to select java message middleware, and the specific use needs to be verified in practice.
