That being said, here’s a review of some of the top use cases for Apache Spark. Use Cases and Examples for Event Streaming with Apache Kafka Exist in Every Industry. However, Stream Processing is also not a tool for all use cases. Moreover, we will discuss stream processing topology in Apache Kafka. Apache Kafka is at the core of many modern data pipelines and excels in use cases where data is created and/or handled in event or record formats. Stream processing can be done in multiple stages where input raw data can be aggregated, enriched, or transformed into new topics for further consumption. It is deployed successfully in mission-critical deployments at scale at silicon valley tech giants, startups, and traditional enterprises. Platforms such as Apache Kafka Streams can help you build fast, scalable stream processing applications, but big data engineers still need to design smart use cases to achieve maximum efficiency. But in the case of Kafka, it is not. Using several case studies, Kleppmann explains how these projects can help you reorient your database architecture around streams and materialized views. It integrates the intelligibility of designing and deploying standard Scala and Java applications with the benefits of Kafka server-side cluster te chnology. Commit Log. Many organizations can benefit from a reliable stream processing system such as Kafka. Flink’s features include support for stream and batch processing, sophisticated state management, event-time processing semantics, and exactly-once consistency guarantees for state. To achieve this, Hudi has embraced similar concepts from stream processing frameworks like Spark Streaming, Pub/Sub systems like Kafka Flink or database replication technologies like Oracle XStream. For the more curious, a more detailed explanation of the benefits of Incremental Processing … Recently, it has added Kafka Streams, a client library for building applications and microservices. We will discuss why you might pick stream processing as your architecture, some of the pros and cons, and a quick-to-deploy reference architecture using Apache Kafka. Streaming is a much more natural model to think about and program those use cases. Since most of our customers work with streaming data, we encounter many different streaming use cases, mostly around operationalizing Kafka/Kinesis streams in the Amazon cloud. Kafka is the de-facto standard for collecting and storing event data. Stream processing is also primed for non-stop data sources, along with fraud detection, and other features that require near-instant reactions. Migrating to Apache Kafka… Kafka: Advantages and Disadvantages Advantages of Apache Kafka. The use cases I’ve just mentioned will certainly benefit from using Kafka Streams. Apache Flink is an excellent choice to develop and run many different types of applications due to its extensive features set.
