Hi,
We are using Apache Ignite's persistence enabled mode. The following is the
only configuration we made.
<bean abstract="true" id="ignite.cfg"
class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="peerClassLoadingEnabled" value="true"/>
<property name="clientMode" value="false"/>
<property name="queryThreadPoolSize" value="16" />
<property name="dataStorageConfiguration">
<bean
class="org.apache.ignite.configuration.DataStorageConfiguration">
<property name="writeThrottlingEnabled" value="true"/>
<property name="defaultDataRegionConfiguration">
<bean
class="org.apache.ignite.configuration.DataRegionConfiguration">
<property name="persistenceEnabled" value="true"/>
</bean>
</property>
</bean>
</property>
</bean>
An exception is thrown when the persistence size reaches to 2.4GB and I saw
the off-heap size growing to the same 2.4GB, when the application is
running. I think 3 GB is maximum amount off-heap can store. The ram is of
16GB and disk storage is having still 100 GB left.
Here is the exception:
class
org.apache.ignite.internal.processors.cache.persistence.StorageException:

Can someone please tell me why it's throwing? Because in production we'd be
getting very big amount of data.
