Kafka Learning Road (ii)--improve the message sending process because Kafka is inherently distributed , a Kafka cluster typically consists of multiple agents. to balance the load, divide the topic into multiple partitions , each agent stores one or more partitions . multiple producers and consumers can produce and get messages at the same time . Process:1.Produc

What's Kafka? Kafka, originally developed by LinkedIn, is a distributed, partitioned, multiple-copy, multiple-subscriber, zookeeper-coordinated distributed logging system (also known as an MQ system), commonly used for Web/nginx logs, access logs, messaging services, and so on, LinkedIn contributed to the Apache Foundation in 2010 and became the top open source project. 1.

of data sent by thousands of clients per second. Scalability: A single cluster can be used as a big data processing hub to centrally process various types of businesses Persistence: messages are persistently stored on disks (Tb-level data can be processed, but the data processing efficiency remains extremely high), and the backup fault tolerance mechanism is available. Distributed: focuses on the big data field and supports distributed processing. clusters can process millions of messages pe

ongoing example application that demonstrates the purpose of Kafka as a messaging server. This example applies the full source code on GitHub. A detailed discussion of it is in the last section of this document.ArchitectureFirst, let me introduce the basic concepts of Kafka. Its architecture consists of the following components: topic (Topic) is a specific type of message flow. The message is a pa

the Kafka topic, the process of subscribing to the message is called the consumer consumer;4, Broker:kafka run on a cluster of one or more servers, each server in the cluster is called broker. (Broker means: Broker, intermediary, agent)So from the macro point of view, the producer (producer) through the network to pub

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

The previous introduction of how to use thrift source production data, today describes how to use Kafka sink consumption data.In fact, in the Flume configuration file has been set up with Kafka sink consumption dataAgent1.sinks.kafkaSink.type =Org.apache.flume.sink.kafka.KafkaSinkagent1.sinks.kafkaSink.topic=TRAFFIC_LOGagent1.sinks.kafkaSink.brokerList=10.208.129.3:9092,10.208.129.4:9092,10.208.129.5:9092ag

Recently opened research Kafka, the following share the Kafka design principle. Kafka is designed to be a unified information gathering platform that collects feedback in real time and needs to be able to support large volumes of data with good fault tolerance.1 , PersistenceKafka using files to store messages directly determines that
