• Welcome to NEJUG

    The New England Java Users Group is open to everyone interested in Java and the JVM. Meetings are usually held on the second Thursday of each month. The meetings and membership are free. We do not hold meetings in July and December. The NEJUG was formed in November 1998. We currently have over 6000 members. Meeting space is limited and we must ask members to register in order to attend meetings. It is common for over 300 people to register for a single meeting! What better way to meet new people interested in Java, development, architecture, or just get your technical questions answered.

      • Event Streaming and Processing using Apache Pulsar

        Thursday September, 15, 2022 06:30 PM
        Zoom Meeting
        Anywhere - MA

      The world is moving at an unprecedented pace and much of it has been powered by the innovations in software and systems.  While event handling, messaging, and processing are not necessarily brand new concepts, the recent emergence in hardware such as virtualizations, multi-core processors, and so on, are in fact pushing the envelope in software design and development, elevating it to higher levels of capabilities never seen before.  In the case of streaming which very often leverages on the underlying messaging mechanism(s) to bring distributed messaging to higher forms of purposes, such as IoT/IIoT applications, AI/ML data pipelines, or even eCommerce recommendations, event streaming platform has indeed become the “glue” in enabling data to flow through disparate systems in the pipeline and in a very dynamic fashion.

      This talk on event streaming is meant for anyone interested in learning about it, and understanding how it fits into the modern software development design and architecture, as well as seeing some of the challenges it faces especially in the Cloud Native environment.  We’ll then take a look at an open source platform - Apache Pulsar, which is poised to become the de facto new generation of distributed messaging and streaming platform that will bring joy to developers, and enable systems and applications to be highly responsive with its true real-time capabilities.

      These will be some of the questions and challenges we will address in this talk:

      • How to maximize impact by delivering excellent work by doing more in less time.
      • How to gain control of our life. Everyone has 24 hours, even Warren Buffet, Bill Gates, and Elon Musk.
      • How to communicate effectively with anyone in 15 minutes build trust.

      • Solution Architects
      • Senior Managers
      • Directors
    • In this example-driven session, we'll review several tips and tricks to make the most out of your Spring development experience. You'll see how these tips fit into a real (albeit small) Spring application and be able to take them with you as you apply them to your project.

      Spring has been the de facto standard framework for Java development for nearly two decades. Over the years, Spring has continued to evolve and adapt to meet the ever-changing requirements of software development. And for nearly half that time, Spring Boot has carried Spring forward, capturing some of the best Spring patterns as auto-configuration.

      As with any framework or language that has this much history and power, there are just as many ways to get it right as there are to get it wrong. How do you know that you are applying Spring in the best way in your application?

      NOTE: Registration is ONLY via MeetUp:

      MeetUp Registration: Creating Resilient Micro-Services.

      The foundation of Application Resiliency is often found in the application code where Fault Tolerance is baked into the application at the time of designing and coding….

      This presentation starts with building resiliency ground-up by baking the basic crucial patterns into the application. Resiliency4j provides the out of the box integration with Spring Boot, a defacto standard micro-service framework.

      The patterns discussed include:

      • Rate Limiter
      • Retry
      • Bulkhead
      • Circuit Breaker
      • Timeouts

  • Spring Boot Best Practices
