+/**
+ * Query execution event.
+ * <p>
+ * Grid events are used for notification about what happens within the grid.
Note that by
+ * design Ignite keeps all events generated on the local node locally and it
provides
+ * APIs for performing a distributed queries across multiple nodes:
+ * <ul>
+ * <li>
+ * {@link
org.apache.ignite.IgniteEvents#remoteQuery(org.apache.ignite.lang.IgnitePredicate,
long, int...)} -
+ * asynchronously querying events occurred on the nodes specified,
including remote nodes.
+ * </li>
+ * <li>
+ * {@link
org.apache.ignite.IgniteEvents#localQuery(org.apache.ignite.lang.IgnitePredicate,
int...)} -
+ * querying only local events stored on this local node.
+ * </li>
+ * <li>
+ * {@link
org.apache.ignite.IgniteEvents#localListen(org.apache.ignite.lang.IgnitePredicate,
int...)} -
+ * listening to local grid events (events from remote nodes not
included).
+ * </li>
+ * </ul>
+ * User can also wait for events using method {@link
org.apache.ignite.IgniteEvents#waitForLocal(org.apache.ignite.lang.IgnitePredicate,
int...)}.
+ * <h1 class="header">Events and Performance</h1>
+ * 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.
+ * <p>
+ * It is <b>highly recommended</b> to enable only those events that your
application logic requires
+ * by using {@link
org.apache.ignite.configuration.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.
+ *
