[jira] [Updated] (CAMEL-8557) The entire LRU Cache is cleared on
eviction of a single entry
[ https://issues.apache.org/jira/browse/CAMEL-8557?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Padmanaban updated CAMEL-8557:
------------------------------
Description:
Use Case:
Using Sftp End point to poll remote directory
Set the following attributes in uri
noop=true
idempotent=true
idempotentRepository=#idemRep
where #idemRep is defined in context xml as below
<bean id="idemRep" class="org.apache.camel.processor.idempotent.MemoryIdempotentRepository">
<property name="cacheSize" value="10" />
</bean>
The number of files in the remote directory is more than 10.
In the above scenario, while trying to add 11th entry into the map, the eldest entry is evicted as expected but soon after the eviction the LRUCache.onEviction clears cache, which i am wondering is not the expected behavior of LRU Cache.
This happens because LRUCache.stopOnEviction is always set to true during the LRUCache instantiation which triggers ServiceHelper.stopService on eviction.
I am trying to understand why we need to reset the cache on eviction.
