| <div class="block">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. For |
| performance reasons Ignite is designed to store all locally produced events |
| locally. These events can be later retrieved using either distributed query: |
| <ul> |
| <li><a href="../../../../../org/apache/ignite/IgniteEvents.html#remoteQuery(org.apache.ignite.lang.IgnitePredicate,%20long,%20int...)"><code>IgniteEvents.remoteQuery(org.apache.ignite.lang.IgnitePredicate, long, int...)</code></a></li> |
| </ul> |
| or local only query: |
| <ul> |
| <li><a href="../../../../../org/apache/ignite/IgniteEvents.html#localQuery(org.apache.ignite.lang.IgnitePredicate,%20int...)"><code>IgniteEvents.localQuery(org.apache.ignite.lang.IgnitePredicate, int...)</code></a></li> |
| </ul> |
| <b>NOTE:</b> this SPI (i.e. methods in this interface) should never be used directly. SPIs provide |
| internal view on the subsystem and is used internally by Ignite kernal. In rare use cases when |
| access to a specific implementation of this SPI is required - an instance of this SPI can be obtained |
| via <a href="../../../../../org/apache/ignite/Ignite.html#configuration()"><code>Ignite.configuration()</code></a> method to check its configuration properties or call other non-SPI |
| methods. Note again that calling methods from this interface on the obtained instance can lead |
| to undefined behavior and explicitly not supported.</div> |
