Kylin use ehcache as the cache solution, by default, it use LRU and
timeToIdleSeconds is set to 1 day. All are configurable in ehcache.xml, by
default it is:

<ehcache maxBytesLocalHeap="2048M">
    <cache name="StorageCache"
           eternal="false"
           timeToIdleSeconds="86400"
           memoryStoreEvictionPolicy="LRU"
            >
        <persistence strategy="none"/>
    </cache>
    <cache name="ExceptionQueryCache"
           eternal="false"
           timeToIdleSeconds="86400"
           memoryStoreEvictionPolicy="LRU"
            >
        <persistence strategy="none"/>
    </cache>
</ehcache>
