Import Kafka source code to Scala IDE and kafkascala After one night of tossing, I finally went to Scala IDE (Eclipse and Sacla plug-in) to view the source code of the Apache Kafka project. My environment is: win7 32-bit, Scala IDE: 4.0.0, Apache Kafka: 0.8.1.1 (added a gradlew. bat file in version 0.8.2) After downloading Scala IDE, I started to find the source

Kafka Learning (1) configuration and simple command usage 1. Introduction to related concepts in Kafka is a distributed message middleware implemented by scala. the concepts involved are as follows: The content transmitted in Kafka is called message. The relationship between topics and messages that are grouped by topic is one-to-many. We call the message publis

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

The following example I only started with a shb01, did not add 139 The general operation of the theme topic (Add a check), through the script kafka-topics.sh to execute Create [Root@shb01 bin]# kafka-topics.sh--create--topic Hello--zookeeper shb01:2181--partition 2--replication-factor 1 Created topic "Hello". --partition 2 means partition --replication-factor 1 represents the replica factor, previously sai

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
