Apache Kafka Learning (i): Kafka Fundamentals 1, what is Kafka. Kafka is a messaging system that uses Scala, originally developed from LinkedIn, as the basis for LinkedIn's active stream (activity stream) and operational data processing pipeline (Pipeline). It has now been used by several different types of companie

I just spent 3 hours last night reading the Journal: a unified concept of real-time data that every software engineer should know about.Today, Kafka is running in a Docker container, several on GitHub, but it's all too complicated.I'll write the simplest Python demo experience for you: Https://github.com/xuqinghan/docker-kafkaCompared with the deployment of Taiga last week, Kafka is worthy of everyone's han

I. Overview of KafkaKafka is a high-throughput distributed publish-subscribe messaging system that handles all the action flow data in a consumer-scale website. This kind of action (web browsing, search and other user actions) is a key factor in many social functions on modern networks. This data is usually resolved by processing logs and log aggregations due to throughput requirements. This is a viable solution for the same log data and offline analysis system as Hadoop, but requires real-time

KAFKA specifies the total amount of data received by topic per minute to monitorRequirements: Get the total amount of data received by Kafka per minute, and save it in a timestamp-topicname-flow format in MySQLDesign ideas:1. Get sum (logsize) at the current point of Kafka and deposit to the specified file file.2. Execute the script again in a minute, get an inst

1:direct Mode Features:1) The direct approach is to directly manipulate the Kafka underlying metadata information so that if the calculation fails, you can reread the data and re-process it. That data is bound to be processed. Pull data, which is the RDD to pull data directly when executing.2) as the direct operation of the Kafka,kafka is the equivalent of your u

Kafka is only a small bond. It is often used for sending and transferring data. In the official case of Kafka, there is no relevant implementation version of PHP in fact. Now the online circulating Kafka of the relevant PHP library, are some of the programming enthusiasts write their own class library, so there will certainly not be too unified interface standard

Preface:　　　　Recently in the research Spark also has Kafka, wants to pass the data which the Kafka end obtains, uses the spark streaming to carry on some computation, but constructs the entire environment is really not easy, therefore hereby writes down this process, shares to everybody, hoped that everybody may take a little detour, can help everybody!Environment Preparation:operating system: ubuntu14.04 LT

Dear friends, I have recently studied kafka and read a lot that kafka may lose messages. I really don't know what scenarios A log system can tolerate the loss of messages. For example, if a real-time log analysis system is used, the log information I see may be incomplete... dear friends, I have recently studied kafka and read a lot that
