  • Apache Kafka also works with external stream processing systems such as Apache Apex, Apache Flink, Apache Spark, Apache Storm and Apache NiFi. Kafka runs on a cluster of one or more servers (called brokers), and the partitions of all topics are distributed across the cluster nodes. Additionally, partitions are replicated to multiple brokers.

  • NiFi is primarily a data flow tool whereas Kafka is a broker for a pub/sub type of use pattern. Kafka is frequently used as the backing mechanism for NiFi flows in a pub/sub architecture, so while they work well together they provide two different functions in a given solution.
  • Apache NiFi is a software project from the Apache Software Foundation designed to automate the flow of data between software systems.Leveraging the concept of Extract, transform, load, it is based on the "NiagaraFiles" software previously developed by the US National Security Agency (NSA), which is also the source of a part of its present name – NiFi.
  • - 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.
  • Sep 25, 2015 · Kafka is a distributed messaging system providing fast, highly scalable and redundant messaging through a pub-sub model. Kafka’s distributed design gives it several advantages. First, Kafka allows a large number of permanent or ad-hoc consumers. Second, Kafka is highly available and resilient to node failures and supports automatic recovery.
