| Region attributes govern the automated management of a region and its entries. |
| |
| 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. |
| |
| ## <a id="specifying-region-attributes" class="no-quick-link"></a>Specifying Region Attributes |
| |
| 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 |
| `RegionShortcut`, `RegionAttributes`, `RegionAttributesFactory`, and `AttributesMutator`. |
| |
| ## <a id="region-shortcuts" class="no-quick-link"></a>Region Shortcuts |
| |
| <%=vars.product_name%> provides predefined, shortcut region attributes settings for your use in `RegionShortcut`. |
| The shortcuts are: |
| |
| `PROXY` |
| > does not store data in the client cache, but connects the region to the servers. |
| |
| `CACHING_PROXY` |
| > stores data in the client cache and connects the region to the servers. |
| |
| `CACHING_PROXY_ENTRY_LRU` |
| > 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. |
| |
| `LOCAL` |
| > stores data in the client cache and does not connect the region to the servers. This is a client-side-only region. |
| |
| `LOCAL_ENTRY_LRU` |
| > 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. |
