1 PrefaceWhat is Apache Nifi? The Nifi website explains the following: "An easy-to-use, robust and reliable data processing and distribution system". In layman's terms, Apache NiFi is an easy-to-use, powerful, and reliable data processing and distribution system designed to support data routing, transformation, and system mediation logic for highly configurable i
Any big data analysis software needs a powerful data pull component, data warehousing system, processing engine, task scheduling engine and process design interface. The focus of Hadoop and Spark is on data storage and task scheduling, and R focuses on the data analysis engine. Data pull components and processes are the main strengths of Nifi.What is Nifi?Apache NiFi is an easy-to-use, powerful and reliable
Apache Nifi is an open source project by the United States National Security Agency (NSA) to the Apache Foundation, which is designed to automate the flow of data between systems. Thanks to its workflow-based programming philosophy, the Nifi is very easy to use, powerful, reliable and highly configurable. Two most important features are its powerful user interface and good data backtracking tools (official

Architecture needs to be designed by people, who are called architects. Many people may not have given the architect the title, but they are doing the work of architecture. We believe that the structure of this work will always need to be done by people, may not be in the short term by the machine to replace. If we do not understand what the
