Apache Kafka Tutorial

Apache Kafka is a distributed stream processing system that provides high scaling, the ability to handle big data, and a unified API. It’s the most popular messaging platform used in Big Data environments believing it is easier to build programs than manage clusters of nodes. Kafka is currently utilized by companies such as eBay, LinkedIn, Intel, and Capital One. The main goal of Kafka is to achieve high performance and scalability. One important concept behind Kafka is its ability to distribute messages across multiple machines for fault tolerance.

The first version of Kafka was released in June 2011. It has seen several major releases. Developers from LinkedIn started to create the project after they recognized a problem with how Apache Hadoop was being used since Hadoop is all about batch processing and doesn’t fit well with real-time streaming data.

Intro to Apache Kafka

Apache Kafka is a distributed streaming platform that can process billions of events daily. The platform is fast and scalable, making it a perfect solution for high-volume service applications. It also has low latency and good throughput because of its design. The platform uses a publish-subscribe messaging model rather than the typical request-response model. It is designed to distribute data across many machines in a fault-tolerant way. By doing so, it can process thousands of messages per second (MPS), with the ability to scale up or down as needed.

Kafka is a modern, distributed, high throughput publish-subscribe system for building a real-time data pipeline and streaming applications.  Its origins are in LinkedIn, which was used internally to handle real-time updates to its website and mobile stack.  It is an open-source project developed by Apache Software Foundation that started around 2011. The platform is written in Java and deployed as a service with its storage runtimes.  It has concepts of batch and user-defined data partitioning.

Confluent Kafka vs Apache Kafka

Confluent Kafka operates quite well, and its performance remains consistent even under huge workloads. Kafka is a fast, scalable, and durable message queue with support for handling millions of messages per second and consuming millions of records from those messages. However, Apache Kafka still beats Confluent Kafka on flexibility. Apache Kafka has more streaming options to provide richer data analysis capabilities by allowing the processing of the data in motion. Apache Kafka also has better integration with third-party tools like Hadoop and Spark due to the project’s open-source nature. Confluent Kafka, on the other hand, offers better operational scalability.

Apache Kafka License

The Apache Kafka license is very permissive and can be used for free or commercial purposes. It is also a contributor’s license with no copyright assignment required. As such, only the original author of the code needs to be legally responsible for that part of the code, and no other party has any rights to any changes made on top of it. The Apache Kafka license permits modification, distribution, and use in software that implements Apache Kafka.

Apache Camel vs Kafka

Apache Camel and Apache Kafka are both popular data stream processing frameworks. Still, they have some key differences that you should be aware of before deciding which to use. The first difference is in how they handle data. Apache Kafka was designed to process large amounts of small, discrete messages sent over time by many producers. Apache Camel is a message broker that can be configured to work with various integration frameworks and programming languages.

Apache Kafka also supplies a higher level of decoupling between producers and consumers, which means that producers can write messages to the Kafka cluster without being concerned about the consumer. This can improve performance by freeing up resources used in managing the consumer. Apache Camel, on the other hand, features a more dynamic approach to processing messages where producers are not required to know anything about the consumer. However, if you need a more static type of messaging where every producer is required to talk to every consumer, then Apache Kafka is your best bet.

Setting Up Apache Kafka on Windows

Setting the Apache Kafka on Windows requires a little more work but is still simple. Here are the steps to install and configure Apache Kafka on Windows:

  1. Check that the JAVA 8 SDK is installed on your PC. 
  2. Apache Kafka Binaries should be downloaded and installed. Download the binaries from the Apache Kafka official download page.
  3. Create a “data” folder and Kafka or Zookeeper folders inside it.
  4. Update the path to the Zookeeper data location in the configuration file. Then, update the path of the Apache Kafka log file in the configuration file.
  5. Start Zookeeper from the command prompt and verify that it launched properly.
  6. Finally, launch Apache Kafka from the command prompt. Run kafka-server-start. bat command using kafka config/server.properties configuration file.

Apache Kafka vs Apache Spark

Kafka is used for the storage and distribution of messages which are processed as they come in from the producer, while Spark is used to process the messages by performing computations on them. One of these two applications can be more efficient depending on what you want to do with your data and how you define this task. Kafka is more focused on logging data, while Spark handles much more than that. Kafka can handle several tasks, and it’s easier to handle. Spark is faster in terms of processing speed because it has one task to perform and focuses on that. This allows the user to use other tools with Spark while they have to use Kafka with other tools as well.

Kafka is more focused on fault tolerance, while Spark has many faults and problems. The default fault tolerance settings for Kafka are better than that for Spark. In the case of Apache Kafka, there is no recovery option, and you have a single point failure where the whole system stops. This kind of error does not occur with Apache Spark as it also allows for auto-recovery settings for its partitions with backups and other options, making it more reliable.
