MQ selection (2022.5.9-5.15)

MQ: Four common types at present (ActiveMQ RabbitMQ RocketMQ Kafka)

General business systems to be introduced MQ, At first, everyone used ActiveMQ, But people don't really use it much anymore , The large throughput scenario is not validated , The community is not very active either , So let's forget it , I personally don't recommend it ;

Later, people began to use RabbitMQ, But it is erlang Language prevents a lot of java Engineers to study and control him , For the company , Almost out of control , But it's true that people are open source , More stable support , It's also very active ;

But there are more and more companies , Will go to use RocketMQ, It's really nice , But I want to remind myself to think about the risk of a sudden yellowness in the community , Have absolute confidence in oneself company technical strength , I recommend RocketMQ, Otherwise go back to old honest practical RabbitMQ Well , People are active open source communities , Absolutely not yellow

So small and medium-sized companies , The technical strength is relatively average , The technical challenges are not particularly high , use RabbitMQ It's a good choice ; Big companies , Infrastructure research and development strength is strong , use RocketMQ It's a good choice

If it is the big data field of real-time computing 、 Log collection and other scenarios , use Kafka It's industry standard , Absolutely no problem , The community is very active , Absolutely not yellow , Moreover, it is the DE facto norm in this field almost all over the world
