hi All,
Regards ContinuousQuery, I notice there is a #setLocal will this meaning CQ
only query against local cache? while this query only have
#setRemoteFilterFactory method.
So the question is will my CQ's local listener only receive event updates from
local cache or entire cluster?
Also the SqlFieldsQuery, we use this to batch update entries in cache, the
frequent may be once several seconds.
The entry may be updated real time, sometime the data may inconsistent seem,
will there any lock/transaction control of this?
We use the JDBC as back-end storage; and notice if we run the instance for
several days, the memory usage keep increase, the performance downgrade very
badly,
And eventually can not be used, from log we receive the ignite node stop event,
but the memory not be reclaimed until we kill the JVM finally.
Our cache defined as:
<property name="cacheMode" value="PARTITIONED"/>
<property name="atomicityMode" value="ATOMIC"/>
<property name="readFromBackup" value="true"/>
<property name="backups" value="1"/>
<property name="readThrough" value="true"/>
<property name="writeThrough" value="true"/>
<property name="writeBehindEnabled" value="true"/>
<property name="writeBehindBatchSize" value="1024"/>
<property name="writeBehindFlushThreadCount" value="1"/>
<property name="storeKeepBinary" value="false"/>
<property name="onheapCacheEnabled" value="true"/>
<property name="memoryPolicyName" value="Asset_Region"/>
<property name="evictionPolicy">
<bean class="org.apache.ignite.cache.eviction.lru.LruEvictionPolicy">
<property name="maxSize" value="#{50000}"/>

</property>

<property name="cacheStoreFactory" ref="storeagefactory"/>
<bean class="org.apache.ignite.configuration.MemoryPolicyConfiguration">
<property name="name" value="Asset_Region"/>
<property name="initialSize" value="#{2L * 1024L * 1024L * 1024L}"/>
<property name="maxSize" value="#{2L * 1024L * 1024L * 1024L}"/>
<property name="pageEvictionMode" value="RANDOM_2_LRU"/>
</bean>
Thanks for your time!
