<div class="block">A partitioned data cache maintains a set of partitions that are DataCache themselves.
Each of the partitioned DataCaches can be individually configured.
However, all partitions must be of the same type. By default, this cache uses
<a href="../../../../org/apache/openjpa/datacache/ConcurrentDataCache.html" title="class in org.apache.openjpa.datacache">ConcurrentDataCache</a> as its partitions.
<br>
This cache can be configured as a plug-in as follows:
<br>
<code>&lt;property name='openjpa.DataCache"
value="partitioned(name=X, PartitionType=concurrent,Partitions='(name=a,cacheSize=100),
(name=b,cacheSize=200)')</code>
<br>
Notice that the individual partition properties are enclosed parentheses, separated by comma
and finally the whole property string is enclosed in single quote.
Each partition must have a non-empty name that are unique among the partitions.
The <a href="../../../../org/apache/openjpa/datacache/CacheDistributionPolicy.html" title="interface in org.apache.openjpa.datacache">policy</a> can return
the name of a partition to distribute the managed instances to be cached in respective partition.
The above configuration will configure a partitioned cache named <code>X</code> with two partitions named
<code>a</code> and <code>b</code> with cache size <code>100</code> and <code>200</code> respectively.
Besides the two partitions, this cache instance itself can store data and referred by its own name
(<code>X</code> in the above example).
