Hi, You can decrease the size of this buffer by setting the system property (default value is 200000): -DIGNITE_ATOMIC_CACHE_DELETE_HISTORY_SIZE=50000
Also you can decrease the number of partitions by adding this to the CacheConfiguraiton: <property name="affinity"> <bean class="org.apache.ignite.cache.affinity.rendezvous.RendezvousAffinityFunction"> <property name="partitions" value="128"/> </bean> </property> Note that to guarantee even data distribution, number of partitions should be at least order of magnitude higher than number of nodes in topology. Please try to play with these parameters and let us know if it helps. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cache-High-Memory-Overhead-caused-by-GridCircularBuffer-Item-instances-tp3682p3686.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
