Reading Time: 2 minutes We store the information in databases so that it can be utilized later for different purposes like reading or updating. While we perform these operations on a record in a database there are good chances of conflicts or collisions. There can be two ways of dealing with such situations: Let’s try to understand these two options with an example. We will use the famous problem Continue Reading
Reading Time: 3 minutes In today’s world of microservices, each microservice has its own set of information stored in some kind of data store. This data store can be either a database or some other system that can retain the data for a period of time. We moved to microservices because we didn’t want one set of functionality not to be impacted by the changes in other functionality. After Continue Reading
Reading Time: 4 minutes In this article, we will implement a Micronaut application written in Java that uses GraphQL to expose the data. Let’s have a quick overview of the GraphQL and Micronaut frameworks before we move on to the implementation. GraphQL “GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the Continue Reading
Reading Time: 3 minutes In this article, we will create an OpenAPI specification file and use it to generate a Java Micronaut server API using the OpenAPI generator. Installing OpenAPI generator We can use the OpenAPI generator using multiple supported workflow integrations like Gradle, Maven, and SBT. Here, we are using the jar option, Download the binary, then place it in the project folder you want to use. To Continue Reading
Reading Time: 4 minutes Overview The ideal framework for continuous delivery and greater resilience is provided by micro-service-oriented architecture. In addition to boosting developer efficiency and improving real-time scalability, they encourage quicker innovation to respond to shifting market conditions. In order to build scalable architectures, we need event-driven and asynchronous integration between microservices. We have multiple options available for asynchronous integration. Kafka is the most popular platform offering characteristics Continue Reading
Reading Time: 3 minutes Depending on the mode that the application is running in, the Quarkus class loading architecture is slightly different. It is a flat class path when running a production application because everything is loaded into the system class loader. For all environment other than production Quarkus uses the class loading architecture outlined here. Bootstrapping Quarkus Quarkus applications are created by the QuarkusBootstrap class in the independent-projects/bootstrap Continue Reading
Reading Time: 2 minutes In this era of microservice based architecture where multiple services are interacting with each other to carry out a transaction, service discovery becomes an integral part as it provides a mechanism to register and find the services. However, it leads to another issue which is “How to select the right service instance in case we have multiple instances of a service running?” . SmallRye Stork Continue Reading
Reading Time: 3 minutes Cloud computing, container technology, or systems for orchestrating containers like Kubernetes weren’t even a concept when Java was created. It was built to maximize throughput (requests/s) at the expense of CPU and memory consumption, resulting in a slow startup time. As the world is moving from monolith to micro-service and serverless architecture where we have multiple instances of a service running scalability issues like startup Continue Reading
Reading Time: 6 minutes Hello! In this article we will continue our journey of understanding Kafka Connect. We will try to understand the architecture and internals of it. We’ve seen that Kafka Connect is a pluggable component that helps to fed data into or from Kafka and hence provides flexible integration pipelines. It is inherently fault tolerant and sacalable. To work with any software component and get the most Continue Reading
Reading Time: 4 minutes Hello! In this article we are going to talk about the Kafka Connect. This page includes why, what and features of Kafka connect. What is Kafka Connect? Kafka Connect, is the pluggable and declarative data integration framework for Kafka. It connects data source/destination to Kafka, letting the rest of the ecosystem do what it is expected from it. It is declarative and makes integration between Kafka Continue Reading
