Originally a distributed messaging system developed by LinkedIn, Kafka became part of Apache, which is written in Scala and is widely used for horizontal scaling and high throughput. At present, more and more open source distributed processing systems such as Cloudera, Apache Storm, spark support and Kafka integration. 1 overview Kafka differs from traditional me

as a stream processor, receive an input stream from one or more topics, output a stream of one or more topics, and effectively convert an input stream into an output stream.The Connector API allows you to build and run reusable producers or consumers, connecting message topics to applications or data systems. For example, a connection to a relational database can get all changes to a table. Kafka's client-to-server communication uses a simple, high-performance, language-independent TCP protocol

= " platinum ' ; Most of the data processing will go through the process of ETL (extract-transform-load), and such a system is usually done through a timed batch operation to complete the data processing, but the time delay caused by batch operation is not acceptable at many times. By using Ksql and Kafka connectors, batch data integration can be transformed into online data integration. For example, through a stream-to-table connection, you c

Message Queuing can reside in memory or on disk, and queues store messages until they are read by the application. With Message Queuing, applications can execute independently-they do not need to know each other's location, or wait for the receiving program to receive

have been designed originally by LinkedIn, it's written in Java and it's now under the Apache project umbrella. Sometimes a technology and you just say:wow that's really done the the-the-it should be. At least I could say this for the purpose I had. What's so special about Kafka are the architecture, it stores the messages in flat files and consumers ask messages based On a offset. Think of it like a MySQL

on the subject or content. The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message. Cluster (Cluster): To simplify system configuration in point-to-point communication mode, MQ provides a Cluster (cluster) solution. A cluster is

asynchronous replication, the data of one master server is fully replicated to another slave server, and the slave server also provides consumption capabilities. In Kafka, it is described as "each server acts as a leader for some of it partitions and a follower for others so load are well balanced Within the cluster. ", simply translated, each server acts as a leader of its own partition and acts as a folloer for the partitions of other servers, thus
