WHAT IS APACHE NIFI?
Apache NiFi is open source software for automating and managing the flow of data between systems. It is a effective and reliable device to process and distribute data. It presents a web-based User Interface for creating, monitoring, & controlling data flows. It has a highly configurable and modifiable data flow process that can alter data at runtime. It is easily extensible through the development of custom components.
General features of Apache NiFi are as follows:
● Apache NiFi gives a web-based user interface, which offers seamless experience between design, control, feedback, and monitoring.
● It is notably configurable. This helps customers with assured delivery, low latency,high throughput, dynamic prioritization, back pressure and modify flows on runtime.
● It additionally offers data provenance module to track and monitor records from the start to the end of the flow.
● Developers can create their very own custom processors and reporting tasks according to their needs.
● NiFi also gives help to secure protocols like SSL, HTTPS, SSH and other encryptions.
● It also helps user and role management and additionally can be configured with LDAP for authorization.
APACHE NIFI ADVANTAGES
