-Defines the type of object to be allowed for the region entry keys. This must be a fully-qualified class name. The attribute ensures that the keys for the region entries are all of the same class. If key-constraint is not used, the region\u2019s keys can be of any class. This attribute, along with value-constraint, is useful for querying and indexing because it provides object type information to the query engine.

-Set the constraint in every cache where you create or update the region entries. For client/server installations, match constraints between client and server and between distributed systems. The constraint is only checked in the cache that does the entry `put` or `create` operation. To avoid deserializing the object, the constraint is not checked when the entry is distributed to other caches.

-## <a id="cc-id_uqb_3qw_bm" class="no-quick-link"></a><cache-loader>
-
-An event-handler plug-in that allows you to program for cache misses. At most, one cache loader can be defined in each member for the region. For distributed regions, a cache loader may be invoked remotely from other members that have the region defined. When an entry get results in a cache miss in a region with a cache loader defined, the loader\u2019s <span class="keyword apiname">load</span> method is called. This method is usually programmed to retrieve data from an outside data source, but it can do anything required by your application.
-
-For partitioned regions, if you want to have a cache loader, install an instance of the cache loader in every data store. Partitioned regions support partitioned loading, where each cache loader loads only the data entries in the local member. If data redundancy is configured, data is loaded only if the local member holds the primary copy.
-
-**API:** `org.apache.geode.cache.RegionFactory.setCacheLoader`
-
-**Example:**
-
-``` pre

-
-## <a id="cc-id_k3w_3qw_bm" class="no-quick-link"></a><cache-writer>
-
-An event-handler plug-in that allows you to receive before-event notification for changes to the region and its entries. It also has the ability to abort events. At most, one cache writer can be defined in each member for the region. A cache writer may be invoked remotely from other members that have the region defined.
-
-**API:** `org.apache.geode.cache.RegionFactory.setCacheWriter`
-
-**Example:**
-
-``` pre
-<region-attributes>

- </cache-writer>
-</region-attributes>
-```
-
-## <a id="cc-cache-listener" class="no-quick-link"></a><cache-listener>
-
-An event-handler plug-in that receives after-event notification of changes to the region and its entries. Any number of cache listeners can be defined for a region in any member. Geode offers several listener types with callbacks to handle data and process events. Depending on the `data-policy` and the `interest-policy` subscription attributes, a cache listener may receive only events that originate in the local cache, or it may receive those events along with events that originate remotely.
-
-Specify the Java class for the cache listener and its initialization parameters with the `<class-name>` and `<parameter>` sub-elements. See [<class-name> and <parameter>](cache_xml.html#class-name_parameter).
-
-**API:** `org.apache.geode.cache.RegionFactory.addCacheListener`

-
-## <a id="cc-eviction-attributes" class="no-quick-link"></a><eviction-attributes>
-
-Specifies whether and how to control a region\u2019s size. Size is controlled by removing least recently used (LRU) entries to make space for new ones. This may be done through destroy or overflow actions. You can configure your region for lru-heap-percentage with an eviction action of local-destroy using Geode\u2019s stored region attributes.
-
-**Default:** Uses the lru-entry-count algorithm.
-
-**API:** `org.apache.geode.cache.RegionFactory.setEvictionAttributes`
-
-**Example:**
-
-``` pre
-<region-attributes>

-Defines a region in the cache. See [<region-attributes>](cache_xml.html#region-attributes) for more details on configuring regions. You can specify zero or more subregions within a region. See [Create and Access Data Subregions](../../basic_config/data_regions/managing_data_regions.html#data_regions__section_jn1_sry_5m) for restrictions on creating subregions. For example, you cannot create a partitioned subregion.

-| name | Specify the name for the region. See [Creating a Region Through the cache.xml File](../../basic_config/data_regions/create_a_region_with_cacheXML.html) for details. | � |
-| refid | Used to apply predefined attributes to the region being defined. If the nested "region-attributes" element has its own "refid", then it will cause the "refid" on the region to be ignored. The "refid" region attriibute can be set to the name of a RegionShortcut or a ClientRegionShortcut. For more information, see [Region Shortcuts and Custom Named Region Attributes](../../basic_config/data_regions/region_shortcuts.html) and [Storing and Retrieving Region Shortcuts and Custom Named Region Attributes](../../basic_config/data_regions/store_retrieve_region_shortcuts.html). | � |

-<td>concurrency-level</td>
-<td>Gives an estimate of the maximum number of application threads that will concurrently access a region entry at one time. This attribute does not apply to partitioned regions. This attribute helps Geode optimize the use of system resources and reduce thread contention. This sets an initial parameter on the underlying <code class="ph codeph">java.util.ConcurrentHashMap</code> used for storing region entries.
