Tonight in conjunction with Hazelcast ( and the Hazelcast User Group ( we’ll be discussing ‘Easy and Fast Stream Processing’ with Neil Stevenson, Senior Solution Architect at Hazelcast.

In this session you will learn all about directed acyclic graph (DAG) and why it is so powerful for Big Data processing. We will walk you through the evolution of Big Data computing from sequential to DAG as well as other techniques such as SP/SC, Cooperative Multithreading, Data Locality, In-Memory sources and sinks, and WaitFree algorithms that power the third generation of Big Data processing.

This presentation will also feature an introduction to Hazelcast JET, an Apache 2 licensed, DAG-based platform for in-memory streaming and fast batch processing that illustrates many of the techniques found in a third generation Big Data platform.

We will walk you through coding common tasks in Java and then step it up to writing full-blown applications in less than a hundred lines of Java code, for applications such as Bitcoin, Twitter sentiment analysis and real-time monitoring of worldwide commercial aircraft.
