Storage for event-based graphs. The event chosen for this demo is quite simple (containing only a timestamp and value). The core is represented by a disruptor tied to a spring-integration channel. For demo purposes, the channel is the simplest one there is, and should be easily reconfigured for any other type (like jms or http, for a stand-alone server).
The demo class of this project is SEGDemo. It instantiates the disruptor, along with input channel and handlers. These handlers store events they receive asynchronously in a H2 memory database (sql provided). A number of handlers (2) was setup just to demo the simplicity of concurrently handling a huge number of events.
=== Unfortunately, the code using Disruptor library blocks when its ring buffer is about to be wrapped around (disruptor setup here has 16384 sequence numbers). We could not wrap this for demo.
