After nearly a month I had the time this afternoon to fetch the source code of Apache Ignite. It is the next step after officially being accepted as a contributor.
I will spend a couple of weeks getting familiar with the code and then I will pick up one of the 'beginner' tickets. Even the longest journeys start with the first steps.
Meanwhile, I sent this past week my proposal for the upcoming Ignite Summit. It is about building business-driven functionality upon the rich computational model that Ignite offers.
Fingers crossed it will get accepted!
