What’s Apache NiFI?
Apache NiFi is a strong open-source Knowledge Ingestion and Distribution framework and extra. It may propagate any information content material from any supply to any vacation spot.
NiFi relies on a unique programming paradigm known as Circulation-Based mostly Programming (FBP). Im not going to clarify the definition of Circulation-Based mostly Programming. As a substitute, I’ll inform how NiFi works, after which you may join it with the definition of Circulation-Based mostly Programming.
How NiFi Works?
NiFi consists of atomic components which could be mixed into teams to construct easy or advanced dataflow.
NiFi as Processors & Course of Teams.
What’s a Processor?
A Processor is an atomic aspect in NiFi which may do some particular job.
The newest model of NiFi have round 280+ processors, and every has its accountability.
Ex. The GetFile processor can learn a file from a selected location, whereas PutFile processor can write a file to a specific location. Like this, we’ve many different processors, every with its distinctive facet.
We’ve processors to Get Knowledge from varied information sources and processors to Write Knowledge to numerous information sources.
The information supply could be virtually something.
It may be any SQL database server like Postgres, or Oracle, or MySQL, or it may be NoSQL databases like MongoDB, or Couchbase, it will also be your search engines like google like Solr or Elastic Search, or it may be your cache servers like Redis or HBase. It may even connect with Kafka Messaging Queue.
NiFi additionally has a wealthy set of processors to attach with Amazon AWS entities likes S3 Buckets and DynamoDB.

NiFi have a processor for nearly every part you want once you sometimes work with information. We’ll go deep into varied sorts of processors obtainable in NiFi in later movies. Even for those who dont discover a proper processor which suit your requirement, NiFi provides a easy strategy to write your customized processors.
Now lets transfer on to the subsequent time period, FlowFile.
What’s a FlowFile?
The precise information in NiFi propagates within the type of a FlowFile. The FlowFile can comprise any information, say CSV, JSON, XML, Plaintext, and it will possibly even be SQL Queries or Binary information.
The FlowFile abstraction is the explanation, NiFi can propagate any information from any supply to any vacation spot. A processor can course of a FlowFile to generate new FlowFile.
The subsequent essential time period is Connections.
In NiFi all processors could be related to create an information move. This hyperlink between processors is known as Connections. Every connection between processors can act as a queue for Circulation Recordsdata as nicely.
The subsequent one is Course of Group and Enter or Output port.
In NiFi, a number of processors are related and mixed right into a Course of Group. When you’ve gotten a posh dataflow, its higher to mix processors into logical course of teams. This helps in higher upkeep of the flows.
Course of Teams can have enter and output ports that are used to maneuver information between them.
The final and ultimate time period you must know for now’s the Controller Providers.
Controller Providers are shared providers that can be utilized by Processors. For instance, a processor which will get and places information to a SQL database can have a Controller Service with the required DB connection particulars.
Controller Service isn’t restricted to DB connections.
