In this post, we will take a look at joins in Kafka Streams. Main goal is to get a better understanding of joins by means of some examples. The examples are taken from the Kafka Streams documentation but we will write some Java Spring Boot applications in order to verify practically what is written in the documentation.
In this post, we will take a look at Kafka Streams. We will give a short introduction, but the main part of the blog will be about writing some simple Java applications. This way, we are going to get more familiar with Kafka Streams from a practical point of view.
In this post, we will take a closer look at Apache Kafka Messaging. We will show how you can easily start a Kafka cluster and how messages can be sent and received by means of CLI and from a Java application. At the end, we will explore how partitions work from a practical point of view.
In this post, we will take a look at how we can make services be aware of each other without knowing their exact location. We will make use of Eureka Server which will act as a Discovery Server. Being Spring fans, we will do so by means of Spring Eureka.
In this post, we will take a look at how we can use Google Cloud Vision from a Spring Boot application. With Google Cloud Vision it is possible to derive all kinds of things from images, like labels, face and text recognition, etc. As a bonus, some examples with Python are provided too.
In this post we will explore how we can use Google Cloud Platform’s (GCP) Pub/Sub service in combination with a Spring Boot application using Spring Integration. We will send a message to a sender application which publishes the message to a Topic where a receiver application receives the messages of a Subscription.
You are looking for an easy way to automatically build your application in the Cloud? Then maybe Google Cloud Platform (GCP) Cloud Build is something for you. In this post, we will build a Spring Boot Maven project with Cloud Build, create a Docker image for it and push it to GCP Container Registry.
In this post, we will take a look at how we can use Google Cloud Platform (GCP) SQL as a database for our Spring Boot application. We will investigate how we can use the Cloud database from our development machine and how we can use it from GCP itself.
In this post we are going to deploy a Spring Boot application to the Google Cloud Platform (GCP) App Engine. First, we will take a look at the differences between the standard and flexible environment of App Engine. After that, we will describe step by step how the deployment to GCP App Engine can be accomplished.
When you pull a Docker image, you will notice that it is pulled as different layers. Also, when you create your own Docker image, several layers are created. In this post we will try to get a better understanding of Docker layers.
