| <p>Region attributes govern the automated management of a region and its entries.</p> |
| |
| <p>Region attribute settings determine where the data resides, how the region is managed in memory, and the automatic loading, distribution, and expiration of region entries.</p> |
| |
| <h2 id="specifying-region-attributes"><a id="specifying-region-attributes" class="no-quick-link"></a>Specifying Region Attributes</h2> |
| |
| <p>Specify region attributes before creating the region. You can do this either through the API or |
| through the declarative XML file. The API includes classes for defining a region’s attributes before |
| creation and for modifying some attributes after creation. For details, see the API for |
| <code>RegionShortcut</code>, <code>RegionAttributes</code>, <code>RegionAttributesFactory</code>, and <code>AttributesMutator</code>.</p> |
| |
| <h2 id="region-shortcuts"><a id="region-shortcuts" class="no-quick-link"></a>Region Shortcuts</h2> |
| |
| <p>Geode provides predefined, shortcut region attributes settings for your use in <code>RegionShortcut</code>. |
| The shortcuts are:</p> |
| |
| <p><code>PROXY</code></p> |
| |
| <blockquote> |
| <p>does not store data in the client cache, but connects the region to the servers.</p> |
| </blockquote> |
| |
| <p><code>CACHING_PROXY</code></p> |
| |
| <blockquote> |
| <p>stores data in the client cache and connects the region to the servers.</p> |
| </blockquote> |
| |
| <p><code>CACHING_PROXY_ENTRY_LRU</code></p> |
| |
| <blockquote> |
| <p>stores data in the client cache and connects the region to the servers. |
| Limits the amount of data stored locally in the client to a default limit of 100,000 entries by ejecting the least recently used (LRU) entries.</p> |
| </blockquote> |
| |
| <p><code>LOCAL</code></p> |
| |
| <blockquote> |
| <p>stores data in the client cache and does not connect the region to the servers. This is a client-side-only region.</p> |
| </blockquote> |
| |
| <p><code>LOCAL_ENTRY_LRU</code></p> |
| |
| <blockquote> |
| <p>stores data in the client cache and does not connect the region to the servers. This is a client-side-only region. |
| Limits the amount of data stored locally in the client to a default limit of 100,000 entries by ejecting the least recently used (LRU) entries.</p> |
