Advanced messaging with Apache ActiveMQ

This document introduces AMQP messaging using RabbitMQ as a broker. It explains that AMQP and RabbitMQ allow applications to communicate asynchronously by sending and receiving messages through a broker, providing decoupling, queueing, load balancing and scalability. It provides details on RabbitMQ as an open source AMQP broker developed by Rabbit Technologies and the AMQP Working Group which maintains the AMQP standard.

Apache Kafka is a fast, scalable, and distributed messaging system. It is designed for high throughput systems and can replace traditional message brokers due to its better throughput, built-in partitioning for scalability, replication for fault tolerance, and ability to handle large message processing applications. Kafka uses topics to organize streams of messages, partitions to distribute data, and replicas to provide redundancy and prevent data loss. It supports reliable messaging patterns including point-to-point and publish-subscribe.

GraalVM is an ecosystem and runtime that provides performance advantages to JVM languages like Java, Scala, Groovy, and Kotlin as well as other languages. It includes a just-in-time compiler called Graal that improves efficiency, polyglot APIs for combining languages, and SDK for embedding languages and creating native images. Installation can be done with the JDK which includes Graal starting with JDK 9, or by directly downloading GraalVM from Oracle's website.

This document discusses building flexible ETL pipelines with Apache Camel on Quarkus. It begins with an overview of what ETL is and the extract, transform, load process. It then discusses what Apache Camel is and how it is an open source integration framework that allows defining routing and mediation rules. The document introduces Camel K and Camel Quarkus, noting that Camel Quarkus brings Camel's integration capabilities to the Quarkus runtime. It argues that Apache Camel and Quarkus is a good combination for efficient ETL due to Camel's easy learning curve and extensibility and Quarkus' benefits like low memory usage and fast startup times. The document concludes with a demo

Kafka is an open source messaging system that can handle massive streams of data in real-time. It is fast, scalable, durable, and fault-tolerant. Kafka is commonly used for stream processing, website activity tracking, metrics collection, and log aggregation. It supports high throughput, reliable delivery, and horizontal scalability. Some examples of real-time use cases for Kafka include website monitoring, network monitoring, fraud detection, and IoT applications.

Codineers Meetup Rosenheim on 2022-10-20 GraalVMs native-image ermöglicht es, JVM Bytecode direkt in Maschinencode zu übersetzen. Das daraus resultierende Executable benötigt keine JVM zum Laufen, startet schneller und verbraucht weniger Speicher als eine traditionelle JVM-Anwendung – ein Segen für Cloud Computing, bei dem jeder CPU-Cycle und Megabyte an RAM bezahlt werden muss. Wäre es nicht großartig, wenn unser Lieblingsframework, Spring Boot, GraalVM direkt out of the box unterstützen würde? In diesem Talk zeigt Moritz Halbritter, Spring Boot committer, was mit Spring Boot 3 und Spring Framework 6 alles möglich sein wird und erlaubt auch einen Blick unter die Motorhaube, um zu sehen, wie das alles implementiert ist.

Speaker: Claus Ibsen - Camel PMC member and top committer

Java on Kubernetes may seem complicated, but after a bit of YAML and Dockerfiles, you will wonder what all that fuss was. But then the performance of your app in 1 CPU/1 GB of RAM makes you wonder. Learn how JVM ergonomics, CPU throttling, and GCs can help increase performance while reducing costs.

This document provides an introduction to Apache ActiveMQ. It discusses how ActiveMQ is a Java Message Service (JMS) and message-oriented middleware that provides asynchronous messaging. It supports cross-language clients and features high performance clustering of brokers for scalability and master-slave configurations for persistence and reliability. The document uses an example of sending a "Hello World" message to demonstrate basic usage of ActiveMQ.

Overview of JMS messaging API. JMS (Java Messaging Service) is an API for asynchronous message based communication between Java based applications. JMS implementations (instances that implement the JMS API) are called JMS providers. JMS defines two messaging domains. Point-to-point queues are typically used between one or multiple message senders and a single message receiver. Topics are multi-point queues where messages are distributed to multiple receivers. As such topics resemble a black board. Like many other message oriented middleware technologies, JMS provides advanced functions like persistent message delivery mode or different message acknowledgment modes. Additionally, messages can be sent and received in a transacted mode thus ensuring that either all or no messages are sent and received. JMS integrates into EJB (Enterprise Java Beans) through message driven beans.

Leandro Melendez from Grafana k6 starts off by providing a grounding in current expectations of what performance engineering and load testing entail. This session defines the modern challenges developers face, including continuous performance principles, Service Level Objectives (SLOs), and Service Level Indicators (SLIs). It delineates best practices and provides hands-on examples using Grafana k6, an open source modern load testing tool.

GraalVM is a high-performance, polyglot VM that can run programs in different languages. It addresses issues with the JVM like performance, startup times, updates, and legacy code. GraalVM uses an optimizing compiler called Graal that can make programs 2-5 times faster than the default C2 compiler through optimizations like inlining and partial escape analysis. Programs can also be compiled to native using SubstrateVM for faster startup times and lower memory footprint, but with less dynamic behavior. Quarkus addresses this by allowing the use of JVM frameworks like Spring and Hibernate within a GraalVM native environment.

This document discusses Java memory leaks. It provides an overview of Java memory management and the behaviors observed with memory leaks. It describes how to generate heap dumps and analyze them using tools like Eclipse Memory Analyzer to identify leaked objects and their referencing paths. Specifically, it outlines how to use MAT to find leak suspects, inspect objects' references, and view thread stacks to locate the root cause of memory leaks.

The document discusses Java Development Kit (JDK) versions 10 and OpenJDK. It provides an overview of JDK 10 including new features like local variable type inference and consolidating the JDK source code into a single repository. It also discusses migrating to JDK 10 and modular development. Finally, it covers OpenJDK, the open source version of Java, including its release cycle and Oracle's OpenJDK builds.

Abstract: "Performance with Native Images" GraalVM is a high-performance polyglot runtime for dynamic, static, and native languages. One of the abilities of GraalVM is to compile Java programs ahead of time into native images that offer performance comparable to running on the JVM but have instant startup times and much lower runtime overhead. Generating native images is proven to work on real-world applications. In this session, you will learn how native images work and what is required to generate them and will look at several examples of compiling programs ahead of time and packaging them into minimal containers. You’ll also see how to configure native image generation, work around the limitations, and configuring your application to use native images.

This document discusses enterprise integration patterns and deployments using Apache ActiveMQ. It provides an overview of key integration concepts like message channels, routing, types of messages, push and pull integration models, request/reply patterns, and job processing. It also covers deployment patterns such as hub and spoke and failover between data centers. Finally, it introduces Apache Camel as a powerful integration framework that supports these patterns and can be used with ActiveMQ.
