What is a Kafka?

Kafka is the freeware distributed sub/pub message system.It was a released in 2011, and it acts as middleware storage between the two applications.Producer stores and writes a messages in a Kafka cluster. On other side, a Consumer consumes the messages from cluster.

What is a RabbitMQ?

RabbitMQ is most commonly used, freeware, and multi-purpose message broker.It was released in a 2007; it is main element in messaging systems.At present,can use it to stream the applications. RabbitMQ can handle the background tasks or acts as message broker between the microservices.It helps a web applications in minimizing a loads. It reduces delivery period of servers for those resources that were time-taking.

RabbitMQ Architecture

Kafka vs RabbitMQ -major differences

Following key differences between the Kafka and RabbitMQ.

1.Architecture:

Kafka Architecture:

Kafka’s architecture uses a high amount of publish-subscribe messages and flow platform that is quick and durable. The tough message store, like logs, uses server clusters that save various records in a topics.Each Kafka message features a value, timestamp, and key. The dumb broker or smart consumer model does not track a consumer messages and returns a unread messages.

RabbitMQ Architecture:

RabbitMQ Architecture uses the all-around message broker that involves are changes in request/reply, pub/sub, and point-to-point communication designs.The utilization of the smart broker and dumb consumer method enables a trustworthy message delivery to a consumers with same speed as a broker controlling a consumer’s state.Through the asynchronous or synchronous communication, RabbitMQ offers enough support for various plugins comprising Node.js, .Net Client Libraries, and Java.

2.Sources:

Kafka:

Develop a Kafka in Scala. In LinkedIn, use it to connect a distinct internal systems. After that, Apache adopted a Kafka in an environment of the products.

RabbitMQ:

It is initially developed for the implementing AMQP, an open wire protocol to message with a robust routing features.Although a java has a messaging system like a JMS, for non-java applications, it is not useful because they need a distributed messaging that is heavily restricted to any inclusion case, either a monolithic or microservice.Therefore, cross-browser resilience becomes a valid for freeware message brokers with an emergence of AMQP.

3.Push/Pull Model:

Kafka:

Kafka uses a Pull model where consumers make a message requests in groups from a specific offset.It also enables a long-pooling that interrupts tight loops when no message crosses an offset.The pull model stays the logical for Kafka because of its partitions. The pull platform offers a message order in block without the conflicting consumers.

RabbitMQ:

RabbitMQ pushes a messages to the consumers that comprise the prefetched restricted configuration that is need to stop the consumer from becoming affected by a multiple messages.And can use a configuration for low latency messaging. The method’s objective is to rapidly distribute a messages separately, besides an assurance that all of them are parallelized be equally, and consumers process messages in the ordered queue.

4.Message Routing:

Kafka:

Kafka does not permit the consumers to filter the messages in as topic before querying them.A subscribed consumer gets all messages in a division of without error.A developer can use Kafka stream job for the reading and filtering messages. Kafka’s stream job pushes a messages to the another topic, and consumers can subscribe to that topic.

RabbitMQ:

RabbitMQ routes a messages to the subscribers of message exchange according to subscriber-based routing rules.Topic Exchange routes the messages according to header named “routing_key.” On other hand, headers exchange routes according to a message headers.Both topic exchange and header messages permit the consumers to define kind of messages they need to receive.

5.Message Retaining:

Kafka:

Kafka retains all messages by design till a configured timeout per topic.Kafka is not be concerned with consumers’ consumption condition in terms of message retention since it serves as message log.

RabbitMQ:

RabbitMQ ejects messages from a storage as early as a consumers consume them. Andb cannot change this behavior, and this is a part of the message brokers.

Apache Kafka vs RabbitMQ – Some other differences are:

    Apache KafkaRabbitMQn
    Basis for Comparison Kafka RabbitMQ
    License Kafka is afreeware through an Apache License 2.0. RabbitMQ is a freeware through Mozilla Public License.
    Developer Experience Kafka has advanced features for the developers; although it only moves the java client, there is an increasing list of a communal freeware clients, natural projects, and an adapter SDK that enables us to develop a system integration. Here “.properties” files perform lot of the configuration. The client libraries of RabbitMQ more appropriately documented and mature and support a Spring, Java, PHP, .NET, Ruby, Python, Javascript, Go, Objective-C, Swift, and Elixir- with the various other development and client tools through a community plugins.
    Client Libraries Kafka has a various libraries are like Python, Ruby, Java, and Node.js. RabbitMQ has a various libraries like Python, Clojure, Python, Node.js, Java, and Go.
    High Availability It supports a High Availability. RabbitMQ supports a High Availability.
    Developed in Kafka is developed in a Scala. RabbitMQ is developed in a Erlang.
    Associated Queues It does not support the associated queues. RabbitMQ supports the associated queues. This feature provides a method of load balancing of single queue throughout the clusters or nodes.
    Hosting and Enterprise Support Kafka is accessible from a CloudKarafka. CloudKarafka offers a free hosted Kafka as a service. RabbitMQ is accessible from a CloudAMQP. The CloudAMQP operates and provides a support to the biggest fleet of RabbitMQ Cluster.
    Difficult Routing Cases It can perform complex routing cases. RabbitMQ cannot perform complex routing cases
    Transactions Kafka endorses those transactions that are demonstrate the “read-process-write” model accomplished from/to a Kafka topics. RabbitMQ does not assure the atomicity even though a transaction carries only one queue.
    Secure Authentication Kafka supports the OAuth2, Standard Authentication, and Kerberos. RabbitMQ supports the OAuth2 and Standard Authentication.

Conclusion

Although Kafka and RabbitMQ are sometimes be exchangeable, their implementations are distinct from the each other. Therefore cannot consider them as a same kinds of tools; Kafka is a distributed streaming platform, and also RabbitMQ is a message broker. Developers and Solution architects must recognize these differences and strongly consider which of these tools they must use in a given scenario.
