We are pleased to bring you the fourth event of the Docklands.LJC; a group within the main London Java Community that focuses on the developer community in and around Docklands that meets on the second Tuesday of each month #dljcjug. Our speakers this month are David Brimley and David Garry.
David Brimley - Distributed Java Systems in Minutes with Hazelcast
Do you want to have quick access to a Java Map that can store terabytes of data? How about if we make the Map partitioned across multiple JVM for fault tolerance and scalability? We’ll also make it in-memory so access is fast.
In this talk we’ll look at how you can use familiar data structures and services such as Maps, Sets, Lists, Queues and Topics in a distributed and highly scalable manner. We’ll be using Hazelcast, which is an open-source, Apache 2 licensed, in-memory data grid. Hazelcast has a very shallow learning curve, we’ll have a distributed system running in minutes. You’ll find that the API is a piece of cake. It is regular Java Collections and Concurrency API, but distributed. Now all your data is stored in memory you’ll also discover how to run various distributed compute operations over it, such as Query, Aggregations and Map Reduce.
The presentation and video recorded from the event are available from InfoQ.
David Garry - Creating Java REST servers from Swagger API definitions
Swagger is a simple but powerful representation of RESTful APIs. This talk will give an introduction to API creation using the Swagger Editor.
Using this API David will show how to generate a REST service in Java, using swagger-codegen to create template Java REST servers with technologies such as Jersey, JAXB and Jackson.
