Event Processing

This section the event processing APIs and how to configure them on top of the space. The relevant APIs include the Notify Container, which wraps the Space Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model. data event session API with event container abstraction, and the Polling Container, which allows you to perform polling receive operations against the Space.
