Apache Kafka is a publish-subscribe messaging application developed by Apache and written in Scala programming language. It is an open-source distributed, partitioned and replicated log service and a message broker application. The design pattern of Kafka is mainly based on the design of the transactional log.
Following is the list of some of the key features of Apache Kafka: 1. Kafka was started by the Apache software and written in Scala programming language. 2. Kafka is a publish-subscribe messaging system built for high throughput and fault tolerance. 3. Kafka has a built-in partition system known as a Topic. 4. Kafka provides the feature of replicat...
Following are some important elements or components available in Apache Kafka: 1. Topic:In Kafka, a topic is a collection or a stream of messages that belong to the same type. 2. Producer:In Kafka, Producers are used to issuing communications and publishing messages to a specific Kafka topic. 3. Consumer:Kafka Consumers are used to subscribing a to...
A consumer group is an exclusive concept of Kafka, which specifies that we will have one or more consumers who consume subscribed topics within each Kafka consumer group.
Apache Kafka is a distributed system. Within the Kafka environment, the ZooKeeper stores offset-related information, which is used to consume a specific topic and by a specific consumer group. The main role of Zookeeper is to build coordination between different nodes in a cluster, but it can also be used to recover from previously committed offset...
In Apache Kafka, the traditional method of message transfer has two ways: 1. Queuing:In the queuing method, a pool of consumers may read messages from the server, and each message goes to one of them. 2. Publish-Subscribe:In the Publish-Subscribe model, messages are broadcasted to all consumers.
Offset is a sequential ID number or a unique id assigned to the messages in the partitions. Offsets are used to identify each message in the partition uniquely with the id available within the partition.
Consumer Group in Kafka is nothing but an exclusive concept of Kafka. Every Kafka consumer group consists of one or more consumers who consume a set of subscribed topics.
Following is a list of key benefits of Apache Kafka above other traditional messaging techniques: 1. Kafka is Fast:Kafka is extremely fast because a single Kafka broker can serve thousands of clients by handling megabytes of reads and writes per second. 2. Kafka is Scalable:In Kafka, we can partition data and streamline over a cluster of machines t...
Following are the four core APIs that Kafka uses: 1. Producer API:In Apache Kafka, the Producer API allows an application to publish a stream of records to one or more Kafka topics. 2. Consumer API:In Apache Kafka, the consumer API allows an application to subscribe to one or more Kafka topics. It also enables the application to process streams of ...
Learn the basics of Apache Kafka, its features, components, benefits, and APIs with this list of 35+ interview questions and answers. Test your knowledge of Kafka with examples and scenarios.
- Explain the architecture of Apache Kafka and how it is designed to achieve high throughput and low latency. Apache Kafka’s architecture consists of four core components: Producers, Brokers, Topics, and Consumers.
- How does Apache Kafka ensure fault tolerance and high availability? Explain the concept of replication and ISR (in-sync replicas). Apache Kafka ensures fault tolerance and high availability through replication, partitioning, and ISR (in-sync replicas).
- What is the role of Kafka Producer API, and how does it interact with the Kafka broker? The Kafka Producer API plays a crucial role in enabling applications to send messages (records) to Kafka topics.
- Describe the role of Kafka Consumer API and how it facilitates parallelism through the use of consumer groups. The Kafka Consumer API plays a crucial role in enabling applications to consume data from Kafka topics.
