- push vs. pull: you tell NiFi each source where it must pull the data, and each destination where it must push the data. With Kafka, you're providing a pipeline or Hub so on the source side each client (producer) must push its data, while on the output, each client (consumer) pulls it's data.

He sees Kafka being used to act as a stream's messaging solution in the middle. NiFi can pump data into Kafka at high speed. All other applications that need the data can pull from Kafka topics at a pace they're comfortable with. "Kafka can scale up to millions of messages per second easily," said Chandrasekhar. Having Kafka in the middle also allows for multiple applications to receive the same data at the same time, making the pipeline more open and pluggable.

Sep 28, 2020 · A Kafka cluster implementation is made up of one or more servers, known as Kafka brokers. Kafka brokers replicate data between themselves in order to cope with specific server failures without losing any messages that have been committed to the Kafka log. Each instance of a Kafka node is configured with the name of a topic. NiFi has processors that can both consume and produce Kafka messages, which allows you to connect the tools quite flexibly. NiFi is not fault-tolerant in that if its node goes down, all of the data on it will be lost unless that exact node can be brought back.

Apache NiFi is a real-time data ingestion platform, which automates the transfer and manages data transfer between disparate systems. Apache Kafka is a high-throughput distributed messaging system that has become one of the most common landing places for data within an organization. Given that Apache NiFi's job is to bring data from wherever it is, to wherever it needs to be, it makes sense that a common use case is to bring data to and from Kafka.
