Presentation of space based programming given at Skills Matter 02 Sep 2009

1. Space based programming [email_address] @gojkoadzic http://gojko.net

4. The idea has been around for a while, but somehow has not caught on… however it’s coming back with a bang!

5. Another language named after a Lovelace

8. Grid computing in 00's

9. Great for computations, but what about transaction processing?

10. Space-based systems will be key for cloud scalability

13. You need a recipient, probably an entity by ID

14. You need a “recipient”, probably an entity by ID A “command” with all the information required to run it

15. You need a “recipient”, probably an entity by ID A “command” with all the information required to run it And an “invoker” to do the job

16. And the command gets executed...

18. You can use many invokers

19. And do loads of work in parallel

20. And you can do something more productive with your time...

22. Space: all your objects

23. Processing units (=partitions)‏

24. GigaSpace data objects [SpaceClass] public class Message { [SpaceID(AutoGenerate=true)] public String MessageId {get; set;} [SpaceRouting] public String MessageType{ get; set;} ... }

29. Example processor [PollingEventDriven(MinConcurrentConsumers = 1, MaxConcurrentConsumers = 4)] internal class MessageProcessor { [EventTemplate] public Message TemplateForThisProcessor { get{ ... } } [DataEventHandler] public Message ProcessMessage(Message message) {.... } }
