Apache Nifi Training

Intro Of Apache NiFi :

The Apache NiFi software enables organizations and systems to automate and manage data flow among them. Data processing and distribution are made easier with this powerful, reliable system. Using the web-based User Interface, data flows can be created, monitored, and controlled. Runtime data modification is possible due to a highly configurable and modifiable data flow process.

Apache NiFi can be easily extended by developing custom components.

It is designed for system administrators and data analysts to manage and automate data flows. By using this program, the user may track the value pair attribute strings, visualize the creation and management of a directed graph of processes, prioritise and use cohesive and loosely coupled components, communicate with the cluster using any node's user interface (UI), make use of network management tools to optimize performance, publish flows by custom templates and share information about loading to specific authorized ports, and implement proxy server in the S2S communication. Complying with compliance policies, optimizing throughput, detecting errors, managing content repositories, prioritizing queues, troubleshooting management, framework management, and supporting Kafka are among the features.

Apache NiFi Training :

A comprehensive Apache NiFi Online Course instructor sponsored training enables you to master the basics of automating dataflows, managing information between systems, streaming analytics, data lakes and constructs, and a range of Apache NiFi real-world data intake methods and projects.

Apache NIFi: Why Use It?

Apache Nifi is used for the following reasons :

• We provide controllers, processors, and other services
• Communication using secure protocols and encryption of content
• Tests quickly and effectively, enabling rapid development
• It allows reusing and combining single-function components to form complex processes
• Allows classloaders to be isolated to make dependency management easier

You Will Learn in this NiFi Training :

• The fundamentals of Big Data, Apache Hadoop, and the NiFi framework
• HDFS and MapReduce high-level architecture
• Installing and integrating NiFi with clusters
• Apache NiFi provides flowfile processing and flow controllers

• Configuring Apache NiFi according to best practices

The Purpose of this Course :

1. If you've never used NiFi, have only accomplished a few tasks within it, or have only seen it in limited contexts, then this guide is for you. Neither this instruction manual nor a reference guide is intended to be exhaustive. In addition to providing substantial information, the User Guide also serves as a very useful reference manual. As opposed to the previous guide, this one is meant to help users gain a thorough understanding of how to work with NiFi to create powerful and agile dataflows quickly and easily.

2. There are a number of sections in this course, some of which are particularly useful to users who are just starting out using NiFi and others that may not be of much interest to others. If you need to navigate to a particular section, feel free to do so.

3. Neither this course nor the company's website goes into great detail about NiFi and assumes that a user has a basic understanding. The Overview documentation contains information of this level.

Term Definitions in This Course :

In order to understand NiFi, readers should familiarize themselves with a few terms. We will give a high-level explanation of those NiFi-specific terms.

FlowFile :

FlowFiles are individual pieces of "User Data" (that is, data that users provide to NiFi for processing and distribution). The two parts of a FlowFile are Attributes and Content. It is the User Data itself that constitutes the content. Each attribute contains a pair of key-value pairs that are associated with the User Data.

Processor :

As a NiFi component, the Processor creates, sends, receives, transforms, routes, splits, merges, and processes FlowFiles. The NiFi dataflow API provides NiFi users with the most powerful and important building blocks.

Why should you go for Apache NiFi Training :

Businesses needing to extract business insights from Big Data are finding success with Apache NiFi Online Course. NiFi is primarily used for sourcing and transforming data from big data lakes and databases. Data from disparate sources can be integrated with this system. With Intellipaat's Apache NiFi classroom training, you'll gain hands-on experience with Apache NiFi projects and be prepared to take on the best jobs in this field.

What Apache NiFi Does ?

Apache NiFi automates the movement of data across disparate systems using an integrated data logistics platform. This solution allows easy data movement between any source and any destination by providing real-time control. It supports a broad range of data sources such as computers, geolocation devices, click streams, files, social feeds, log files and videos as well as a variety of other formats, schemas, protocols, speeds and sizes. Data can be moved around with it, similarly to how Fedex, UPS, and other delivery services move packages. Apache NiFi is like those services, as well. You can track your data in real time, just like you can track a package delivery.

Implementing Apache NiFi using Best Practices :

• In NiFi, it is ideal to separate the test, development, and production environments
• Group your processes according to their functions
• Make use of comments, labels, and naming conventions
• Ingestion, testing, and monitoring are the key components of your projects
• Don't use the same name for all variables

Apache NiFi -Key Concepts :

Apache NiFi is based on the following concepts: −

1. Process Group :A NiFi flow group helps users to organize and manage their flows in a hierarchical manner.

2. Flow : In this arrangement, different processors are connected to the same source of data so that data can be transferred and modified between them. Processor modules fetch or store data from sourcing systems. They are integrated into Java applications. A flowfile may also contain other processors that add attributes and change content.

3. Flowfile : In NiFi, this object represents the picking of data from the source system that is represented by the single object. A NiFi processor makes modifications to a flow file while it moves from a source processor to a destination processor. In a flow, different processors perform different actions on flowfiles, like CREATE, CLONE, and RECEIVE.

4. Event : As NiFi Flows traverse through, events appear which represent the changes in flowfile. A data provenance is maintained for these events. Repository is available, as well as a user interface that allows users to check the flowfile information and diagnose any problems that might arise.

Apache NiFi Advantages :

• Data can be fetched from distant machines using Apache NiFi using SFTP and lineage has been assured.

• Using multiple Nodes with the same flow to process different data is one of the ways Apache NiFi supports clustering, which improves data processing performance.

• Other modules, such as user security policies, process group security policies, and others are included.

• UI interactions with NiFi can also be secured with HTTPS, which makes their use of the app more secure.

• Users can also make custom plugins for virtually any data system NiFi supports, and it has 188 processors.

Features :

Graph-based data routing, transformation, and mediation logic are supported by Apache NiFi with a powerful and scalable interface. Apache NiFi can achieve the following high-level capabilities and objectives :

• • User-interface provided by the web
  • An experience that seamlessly combines design, control, feedback, and monitoring
  • Easily customizable
  • Loss tolerance versus delivery guarantee
  • High throughput versus low latency
  • Prioritization based on dynamic factors
  • Changes can be made at runtime to the flow
  • Insufficiency of back pressure
  • An explanation of how the data was collected
  • Follow the flow of data from beginning to end
  • Extensible design
