public class DataStorageConfiguration extends Object implements Serializable
getPageSize()
). An individual page can store one or many cache key-value entries
that allows reusing the memory in the most efficient way and avoid memory fragmentation issues.
By default, the durable memory allocates a single expandable data region with default settings. All the caches that
will be configured in an application will be mapped to this data region by default, thus, all the cache data will
reside in that data region. Parameters of default data region can be changed by setting
setDefaultDataRegionConfiguration(DataRegionConfiguration)
.
Other data regions (except default) can be configured with
setDataRegionConfigurations(DataRegionConfiguration...)
.
Data region can be used in memory-only mode, or in persistent mode, when memory is used as a caching layer for disk.
Persistence for data region can be turned on with DataRegionConfiguration.setPersistenceEnabled(boolean)
flag. To learn more about data regions refer to DataRegionConfiguration
documentation.
Sample configuration below shows how to make 5 GB data regions the default one for Apache Ignite:
<property name="dataStorageConfiguration">
<bean class="org.apache.ignite.configuration.DataStorageConfiguration">
<property name="systemCacheInitialSize" value="#{100L * 1024 * 1024}"/>
<property name="defaultDataRegionConfiguration">

<property name="initialSize" value="#{5L * 1024 * 1024 * 1024}"/>
