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
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

1. File System Description
File systems are generally divided into two types: system and user. System-level file systems: ext3, ext4, DFS, NTFS, etc ,, I will not introduce the complicated distributed or system-level file system,
The architecture design of the Kafka file system is deeply analyzed from the perspective of the high performance of the Kafka architecture.
