Interface GridEventStorageSpi

All Superinterfaces:

GridSpi

All Known Implementing Classes:

@Apache20LicenseCompatible
public interface GridEventStorageSpi
extends GridSpi

This SPI provides local node events storage. SPI allows for recording local node events and querying recorded local events. Every node during its life-cycle goes through a serious of events such as task deployment, task execution, job execution, etc. (see GridEventType for full list of event types). For performance reasons GridGain is designed to store all locally produced events locally. These events can be later retrieved using either distributed query:

• Grid.queryEvents(GridEventFilter, Collection, long)

or local only query:

• Grid.queryLocalEvents(GridEventFilter)
