[jira] [Commented] (IGNITE-12142) Ignite ignores that on-heap store
is disabled when putting values through near cache
[ https://issues.apache.org/jira/browse/IGNITE-12142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16923296#comment-16923296 ]
Bartłomiej Stefański commented on IGNITE-12142:
-----------------------------------------------
Also, I tested scenario when on-heap store and lru eviction are enabled on server and client nodes:
{code:java}
...
<property name="onheapCacheEnabled" value="true"/>
<property name="evictionPolicy">
<bean class="org.apache.ignite.cache.eviction.lru.LruEvictionPolicy">
<property name="maxSize" value="2000"/>
</bean>
</property>
...
{code}
After putting 20k entries to cache through client node:
{code:java}
Nodes for: myCache(@c0)

{code}
Heap of server node (@n0) contains 20k entries, but should contain only 2k (max size configured in eviction policy). If I put values directly on server node eviction works fine:
{code:java}
Nodes for: myCache(@c0)
