Introduced
Kafka is a distributed, partitioned, replicable messaging system. It provides the functionality of a common messaging system, but has its own unique design. What does this unique design look like?
Let's first look at a few basic messaging system terms:
Kafka the message to topic as a unit.• The program that will release the message to Kafka topic
Today, we're going to start talking about RABBITMQ a little bit more advanced. Understanding this step is very useful for us in designing highly concurrent systems. Of course, you can also use Kafka. But still forget, there are a few hard conditions do not support, or use RABBITMQ bar.Circular distribution:Initiates a send end to send a message to the queue, at w

Introduction to Kafka
Kafka is a high-throughput distributed Message Queue with high performance, persistence, multi-copy backup, and horizontal scaling capabilities. It is usually used on big data and stream processing platforms. Message Queues all have the producer/consumer concept. The producer writes messages to the queue, while the consumer obtains messages from the queue. It is generally used for deco
Kafka is a distributed streaming platform, what exactly does it mean.
The streaming platform has the following three main functions:☆ Publish and subscribe stream records, similar to Message Queuing or enterprise-level messaging systems.☆ You store stream records in a fault-tolerant manner.☆ Timely processing when the flow record is generated.
Kafka is used in two major categories of applications:☆ Establis

Kafka is a distributed publish-subscribe messaging system, which is simply a message queue, and the benefit is that the data is persisted to disk (the focus of this article is not to introduce Kafka, not much to say). Kafka usage scenarios are still relatively large, such as buffer queues between asynchronous systems, and in many scenarios we will design as follo

To demonstrate the effect of the cluster, a virtual machine (window 7) is prepared, and a single IP multi-node zookeeper cluster is built in the virtual machine (the same is true for multiple IP nodes), and Kafka is installed in both native (Win 7) and virtual machines.Pre-preparation instructions:1. Three zookeeper servers, the local installation of one as Server1, virtual machine installation two (single IP)2. Three
RABBITMQ Cluster High AvailabilityRABBITMQ is developed with Erlang, which is very handy because Erlang is inherently a distributed language, but it does not natively support load balancing.Rabbit mode is roughly divided into the following three types: Single mode, normal mode, mirror modeSingle mode: The simplest case, non-clustered mode.There's nothing to say.Normal mode: The default cluster mode.For a queue, the message entity exists only in one of
a Erlang installation1.RabbitMQ is based on Erlang, so you must first configure the Erlang environment.Download the latest Erlang installation package from Erlang's official website http://www.erlang.org/download.html, the version of Linux and MacOSX download is http://www.erlang.org/download.html2. Then unzip the downloaded GZ package TAR-ZXVF *.tar.gz3.cd into the extracted folder4. Execute./configure--prefix=/opt/erlang will start compiling the i
"Introduction" Have you ever encountered two (multiple) systems that need to synchronize certain data through a timed task? Are you struggling with the problem of calling and communicating between different processes of heterogeneous systems? If so, congratulations, the messaging service makes it easy for you to solve these problems. The Messaging service specializes in solving data exchange (message notification/communication) issues between multiple systems and heterogeneous systems, and you c
