Quarkus – the Kubernetes Native Java Framework
Cheat Sheet Quarkus – the Kubernetes Native Java Framework by Alex Soto Start-Up What is Quarkus? Quarkus is a Kubernetes Native Java stack tailored for GraalVM & OpenJDK HotSpot that makes Java programs run 10X faster and 100X smaller. It also improves the developer ex- perience by adding features like live reloading/debugging and persistence with Panache. Requirements • Java 8 • Maven 3.5.3+ (recommended Maven 3.6.X) • GraalVM 19 or Docker (optional for native compilation) Scaffolding a Quarkus application You can create a minimal Quarkus application using a Maven goal. This goal creates a mi- nimal endpoint, a test and Docker resources: mvn io.quarkus:quarkus-maven-plugin:0.19.1:create \ -DprojectGroupId=org.alexsotob \ -DprojectArtifactId=jax \ -DclassName="org.alexsotob.quickstart.GreetingResource" \ -Dpath="/hello" Start Quarkus in live reload (dev) mode: ./mvnw compile quarkus:dev You can request the provided endpoint: curl http://localhost:8080/hello Live Reload You can make any change on any (Java) resource and, if the Quarkus application was star- ted in live reload mode, the change will be automatically reflected without having to re- compile or repackage the application. Try it by changing the output value of the src/main/- java/org/alexsotob/quickstart/GreetingResource.java class. Packaging Run ./mvnw package to generate a jar file called jax-1.0-SNAPSHOT-runner.jar that contains the application and lib directory containing required dependencies for running the applicati- on. Quarkus, unlike other solutions, does not create a fat jar so as to be Docker layers fri- endly. Both jar file and lib folder should be placed together in the same directory. -

Getting Started with Apache Avro
Getting Started with Apache Avro By Reeshu Patel Getting Started with Apache Avro 1 Introduction Apache Avro Apache Avro is a remote procedure call and serialization framework developed with Apache's Hadoop project. This is uses JSON for defining data types and protocols, and tend to serializes data in a compact binary format. In other words, Apache Avro is a data serialization system. Its frist native use is in Apache Hadoop, where it's provide both a serialization format for persistent data, and a correct format for communication between Hadoop nodes, and from client programs to the apache Hadoop services. Avro is a data serialization system.It'sprovides: Rich data structures. A compact, fast, binary data format. A container file, to store persistent data. Remote procedure call . It's easily integration with dynamic languages. Code generation is not mendetory to read or write data files nor to use or implement Remote procedure call protocols. Code generation is as an optional optimization, only worth implementing for statically typewritten languages. Schemas of Apache Avro When Apache avro data is read, the schema use when writing it's always present. This permits every datum to be written in no per-value overheads, creating serialization both fast and small. It also facilitates used dynamic, scripting languages, and data, together with it's schema, is fully itself-describing. 2 Getting Started with Apache Avro When Apache avro data is storein a file, it's schema is store with it, so that files may be processe later by any program. If the program is reading the data expects a different schema this can be simply resolved, since twice schemas are present. -
