What is Apache Nifi?
Apache Nifi is an open source project used to create ETL/ELT processes using data flow i.e., instead of using Python code to create ETL/ELT processes, Apache Nifi uses ready to use software entity called a "processor" to create ETL/ELT processes with Nifi user interface (UI).
A processor can be getting data from data sources e.g., MongoDB, Apache Kafka, coverting data to Parquet file format, or writing data to sinks.
