It’s no secret that Kafka was the first event-streaming platform that helped organizations effectively harness the power of real-time data. Over the years, it has become the go-to solution for handling and processing streaming data for quick decision-making. Despite its widespread adoption, Kafka may not always be the best choice for message queuing. Kafka requires a lot of Memory and Storage, so setting up a multi-node cluster for testing purposes on a standalone workstation can be tricky. Organizations and users are thus shifting to Kafka Alternatives that are more user-friendly.

Prerequisites

  • A basic understanding of data streaming infrastructure 

Understanding Kafka 

Kafka Alternatives: Kafka logo

Kafka is an Open-Source software program that lets you store, read, and analyze streaming data. It is free for everyone to use and is supported by a large community of users and developers who consistently contribute to new features, updates, and support. As a “Distributed” system, Kafka can run on several servers to leverage different servers’ processing power and storage capacity.

As a part of its original design, Kafka was intended to monitor the behavior of users on websites. A complete picture of user behavior can be obtained by analyzing clickstream data after every session (where do users navigate on the website and what functions they use). Using this information, you can predict which articles or products a visitor would be interested in.

To further extend its capabilities, Apache Kafka supports integrations with Apache Flume, Apache Spark Streaming, Apache Storm, and HBase for real-time research, analysis, and streaming data processing to extend its capabilities further.

Key Features of Kafka 

Let us dive deep into some of the key features of Apache Kafka.

  • Scalability: Using Kafka, you can scale in all four dimensions: Event Producer, Event Processor, Event Consumer, and Event Connector without facing any downtime.
  • Persistent for Short Run: The retention policy of Kafka is, by default, seven days, which can be changed as per user. Using Kafka, you can store your data for Short Periods before erasing the oldest values.
  • Replication: Kafka MirrorMaker supports cluster replication. Multiple Data Centers or Cloud Regions can receive messages via replication features. 
  • Reliability and Durability: Kafka maintains a replica of its messages on disk, allowing intra-cluster replication. This makes Kafka a highly durable messaging system. 
  • Extensibility: Since Kafka can be plugged into several applications, you can seamlessly add new functionality and execute your initiatives.
