April 2018 Meeting Information

April 10, 2018
Gambling With Leopards

We are happy to announce that Java Champion and co-founder of jClarity, Ben Evans will be our special guest for this month's meeting.

This is a fairly light-hearted talk, that describes an experience report of a real application - BetLeopard. This application is a reference implementation of an open-source horse racing engine that uses distributed computation.

Ben will showcase several different ways of approaching a calcuation problem - first by using Java 8 lambdas, then by using Hazelcast IMDG with Apache Spark for processing and then again with Hazelcast Jet. Ben will also consider a more advanced example - basic real-time risk calculation. The talk covers processing techniques, some domain design, serialization as well as showing how to get started with Spark and Jet.
