Questions & Answers

Q: How does Apache Kafka ensure high performance and scalability?

Apache Kafka achieves high performance and scalability by distributing the records produced across a cluster of servers or data centers, allowing a large volume of users to use the application without noticeable lag in performance. It also replicates and partitions the data records intelligently.

Q: How does Apache Kafka decouple system dependencies?

With Apache Kafka, instead of building complex integrations between different services in an application, events are streamed and services can choose to listen to the relevant events. This decouples the dependencies between services, allowing them to act independently and improving development speed.

Q: What are some use cases for Apache Kafka?

Some notable use cases for Apache Kafka include decoupling system dependencies, location tracking (e.g., ride-sharing services), and data gathering for analytics or real-time recommendations in applications like music streaming services.

Q: What are the core APIs of Apache Kafka?

Apache Kafka is built on four core APIs. The producer API allows applications to produce streams of data records. The consumer API subscribes to topics and ingests the data. The streams API enables real-time transformation and analysis of data. The connector API allows for reusable producers and consumers.
