The jChampions Watch Party and Live Talk with Java Champion Mary Grygleski

Join us on January 24th as the Dublin Java User Group hosts day four of the jChampions Conference Watch Party, finishing with two talks with Chicago-based Java Champion Mary Grygleski LIVE and IN-PERSON.

14:00 - 18:00 The Watch Party.
We invite you to join members of the Dublin Java Community at the jChampions Watch Party here at TechMeetup.Space in Dublin City Centre. At this event, you will see Java Champions Grace Jansen, Sebastian Daschner, Bazlur Rahman, Paul and Gail Anderson, Emily Jiang, and Henri Tremblay present a variety of live on-line sessions.

Tickets for the watch party are free but booking is essential.

18:45 LIVE INPERSON WITH MARY GRYGLESKI
Building An Efficient Streaming Data Pipeline with Apache Pulsar and Apache Cassandra
Event Streaming is one of the most important software technologies in the current computing era as it enables systems to process huge volumes of data in blazingly high speed and in real-time. It is indeed the "glue" that can connect data to flow through disparate systems and pipelines that are typical in cloud environments. Leveraging on the Pub/Sub pattern for the message flow, and designed with the cloud in mind, Apache Pulsar has emerged as a powerful distributed messaging and event streaming platform in the recent years. With its flexible and decoupled messaging style, it can integrate and work well with many other modern-day libraries and frameworks.

In this session, we will build a modern, efficient streaming data pipeline using Apache Pulsar and Apache Cassandra. Apache Pulsar will handle the data ingest. The external data that comes in will be used for further processing by Pulsar Functions that will in turn reference the tables in Cassandra as the data lookup sources. The results of the transformed data will then be egressed and sent to an Astra DB sink. We will also examine to see how we can further optimize the entire processing pipeline.

20:00: LIVE INPERSON WITH MARY GRYGLESKI
Event Messaging and Streaming with Apache Pulsar
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.

Mary's talk is live-streamed as part of the jChampions conference running for four days, Thursday 19th, Friday 20th, Monday 23rd, and Tuesday 24th January. Other presentations are by Andrew Greenstein, Antoine Sabot-Durand, Anton Rodriguez, Barry Burd, Bazlur Rahman, Brian Benz, Cesar Hernandez, Emily Jiang, Gail Anderson, Grace Jansen, Haim Yadid, Heinz Kabutz, Henri Tremblay, Holly Cummins, Ixchel Ruiz, Kirk Pepperdine, Maria Arias de Reyna Dominguez, Mario Fusco, Mohamed Taman, Ondro Mihalyi, Otavio Santana, Paul Anderson, Peter Lawrey, Rafael Del Nero, Rustam Mehmandarov, Sandra Parsick, Sebastian Daschner, and Victor Orozco.
