Emulating Apache Kafka with Amazon SNS and SQSTech by Sunny Srinidhi - January 22, 2020January 24, 20200 We’ll learn how to introduce the concept of consumer groups from Kafka in the AWS world using Amazon SNS and Amazon SQS.
Apache Kafka Streams and Tables, the stream-table dualityData ScienceTech by Sunny Srinidhi - October 1, 2019February 25, 20200 In the previous post, we tried to understand the basics of Apache's Kafka Streams. In this post, we'll build on that knowledge and see how Kafka Streams can be used both as streams and tables. Stream processing has become very common in most modern applications today. You'll have a minimum of one stream coming into your system to be processed. And depending on your application, it'll mostly be stateless. But that's not the case with all applications. We'll have some sort of data enrichment going on in between streams. Suppose you have one stream of user activity coming in. You'll ideally have a user ID attached to each fact in that stream. But down the pipeline, user ID is
How you can improve your backend services’ performance using Apache KafkaTech by Sunny Srinidhi - November 27, 2018February 25, 20201 In most real world applications, we have a RESTful API service facing various client applications and a collection of backend services which process the data coming from those clients. Depending on the application, the architecture might have various services spread across multiple clusters of servers, and some form of queue or messaging service gluing them together. Today, we're going to talk about one such messaging service - Apache Kafka - and how it can improve the performance of your services. We're going to assume that we have at least two microservices, one for the APIs that are exposed to the world, and one which processes the requests coming in from the API microservice, but in an async fashion. Because this is
Simple Apache Kafka Producer and Consumer using Spring BootTech by Sunny Srinidhi - November 23, 2018March 2, 20202 Originally published here: https://medium.com/@contactsunny/simple-apache-kafka-producer-and-consumer-using-spring-boot-41be672f4e2b Before I even start talking about Apache Kafka here, let me answer your question after you read the topic — aren’t there enough posts and guides about this topic already? Yes, there are plenty of reference documents and how-to posts about how to create Kafka producers and consumers in a Spring Boot application. Then why am I writing another post about this? Well, in the future, I’ll be talking about some advanced stuff, in the data science space. Apache Kafka is one of the most used technologies and tools in this space. It kind of becomes important to know how to work with Apache Kafka in a real-world application. So this is an introductory post to the technology, which we’ll be
