## Interface EventType

-     public interface EventType

  Contains event type constants. The decision to use class and not enumeration dictated by allowing users to create their own events and/or event types which would be impossible with enumerations.

  Note that this interface defines not only individual type constants but arrays of types as well to be conveniently used with `IgniteEvents.localListen(IgnitePredicate, int...)` method:

  - `EVTS_CACHE`
  - `EVTS_CACHE_LIFECYCLE`
  - `EVTS_CACHE_REBALANCE`
  - `EVTS_CACHE_QUERY`
  - `EVTS_CHECKPOINT`
  - `EVTS_DEPLOYMENT`
  - `EVTS_DISCOVERY`
  - `EVTS_DISCOVERY_ALL`
  - `EVTS_ERROR`
  - `EVTS_JOB_EXECUTION`
  - `EVTS_TASK_EXECUTION`

  NOTE: all types in range from 1 to 1000 are reserved for internal Ignite events and should not be used by user-defined events.

  # Events and Performance

  Note that by default all events in Ignite are enabled and therefore generated and stored by whatever event storage SPI is configured. Ignite can and often does generate thousands events per seconds under the load and therefore it creates a significant additional load on the system. If these events are not needed by the application this load is unnecessary and leads to significant performance degradation.

  It is highly recommended to enable only those events that your application logic requires by using either `IgniteConfiguration.getIncludeEventTypes()` method in Ignite configuration. Note that certain events are required for Ignite's internal operations and such events will still be generated but not stored by event storage SPI if they are disabled in Ignite configuration.

      Built-in event type: intermediate state of a job or task, so-called checkpoint, was saved.
