Recently done a project need to use RABBITMQ, according to their own previous article to install the test, are OK, but the actual use of the process found a lot of problems;The scenario is this:I built 10 queues, wrote a loop, the purpose is to write 30,000 data to each queue, the result is a test of n times, the program is written to the fourth queue, it was killed; after the top command, monitoring memory, the program in the process of execution, the CPU utilization reached more than 70%, PHP

about the message. The message body carries the data or payload of the application. Depending on the type of payload, messages can be divided into several types, each carrying: simple text (textmessage), serializable object (objectmessage), attribute collection (mapmessage), Byte Stream (bytesmessage), The original value stream (Streammessage), as well as a message with no payload.Specific products: apache-activemq and so on;3,amqpAMQP (Advanced message Queuing Protocol) He is an application-le

Kafka is a distributed MQ system developed by LinkedIn and open source, and is now an Apache incubation project.
