Event Processing

This section describes the event processing APIs and how to configure them on top of 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.. The relevant APIs include the Notify Container, which wraps the Space data event session API with event container abstraction, and the Polling Container, which allows you to perform polling receive operations against the Space.

Events that are received by the polling and notify containers are handled by the Event Listener, which is a Space Data Event Listener and the Event Exception Listener.

Regarding FIFO Ordering, GigaSpaces supports both non-ordered Entries and FIFO FIFO is an acronym for first in, first out, a method for organizing the manipulation of a data structure where the oldest entry, or "head" of the queue, is processed first. ordered Entries when performing Space operations. GigaSpaces also includes JMS message support that is built on top of the core Space architecture.
