| <div class="block">This class allows defining custom data regions' configurations with various parameters for Apache Ignite |
| page memory (see <a href="../../../../org/apache/ignite/configuration/DataStorageConfiguration.html" title="class in org.apache.ignite.configuration"><code>DataStorageConfiguration</code></a>. For each configured data region Apache Ignite instantiates |
| respective memory regions with different parameters like maximum size, eviction policy, swapping options, |
| persistent mode flag, etc. |
| An Apache Ignite cache can be mapped to a particular region using |
| <a href="../../../../org/apache/ignite/configuration/CacheConfiguration.html#setDataRegionName-java.lang.String-"><code>CacheConfiguration.setDataRegionName(String)</code></a> method. |
