1. Background information Many of the company's platforms generate a large number of logs (typically streaming data, such as the PV of search engines, queries, etc.), which require a specific log system, which in general requires the following characteristics: (1) Construct the bridge of application system and analysis system, and decouple the correlation between them; (2) support the near real-time on-line analysis system and the off-line analysis system similar to Hadoop; (3) with high scalabi

Background:In the era of big data, we are faced with several challenges, such as business, social, search, browsing and other information factories, which are constantly producing various kinds of information in today's society: How to collect these huge information how to analyze how it is done in time as above two points The above challenges form a business demand model, which is the information of producer production (produce), consumer consumption (consume) (processing analysis), an

Install Kafka on CentOS 7Introduction Kafka is a high-throughput distributed publish/subscribe message system. It can replace traditional message queues for decoupling Data Processing and caching unprocessed messages. It also has a higher throughput, it supports partitioning, multiple copies, and redundancy, and is widely used in large-scale message data processing applications.

, it is quite simple, but not convenient, we need to deploy flume on each server to monitor, in case the target log file IO exception (such as format change, file name change, File is locked), it is also very painful, so we'd better let the log sent directly through the socket, rather than local, so that not only reduce the target server disk usage, but also effective to prevent file IO exception, and Kafka is a better solution, The specific architect

consumers, and the cleanup process itself may lose information. So, you publish the raw data stream, and then you create a derived stream that finishes the cleanup work based on it. Stream processingOne of the goals of the streaming data platform is to stream data between data systems, and another goal is to stream data as it arrives. In a streaming data platform, stream processing can simply be modeled as transitions between streams, as shown in: There are many benefits of republishing p
