Hi,
I am using JCS for Disk Based Caching. I don't want to use memory cache. So I set the configuration like this:
##############################################################
##### Default Region Configuration
jcs.default=DC
jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.default.cacheattributes.MaxObjects=0
jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
##############################################################
##### CACHE REGIONS
jcs.region.myRegion1=DC
jcs.region.myRegion1.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.region.myRegion1.cacheattributes.MaxObjects=0
jcs.region.myRegion1.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
jcs.region.myRegion1.cacheattributes.MaxSpoolPerRun=100
##############################################################
##### AUXILIARY CACHES
# Indexed Disk Cache
jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFactory
jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheAttributes
jcs.auxiliary.DC.attributes.DiskPath=target/test-sandbox/indexed-disk-cache
jcs.auxiliary.DC.attributes.MaxPurgatorySize=1000
jcs.auxiliary.DC.attributes.MaxKeySize=1000
jcs.auxiliary.DC.attributes.MaxRecycleBinSize=5000
jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000
jcs.auxiliary.DC.attributes.OptimizeOnShutdown=true
jcs.auxiliary.DC.attributes.EventQueueType=POOLED
jcs.auxiliary.DC.attributes.EventQueuePoolName=disk_cache_event_queue
##############################################################
################## OPTIONAL THREAD POOL CONFIGURATION ########
# Disk Cache Event Queue Pool
thread_pool.disk_cache_event_queue.useBoundary=false
thread_pool.remote_cache_client.maximumPoolSize=15
thread_pool.disk_cache_event_queue.minimumPoolSize=1
thread_pool.disk_cache_event_queue.keepAliveTime=3500
thread_pool.disk_cache_event_queue.startUpSize=1
I set max object 0 so that all items are cache in disk.
jcs.default.cacheattributes.MaxObjects=0
As I set the maxkeysize=1000, after writing 1000 items, I am calling jcs.freeMemoryElements(1000), so that all the items are successfully writen to disk. But this method throwing exception: Update: Last item null.
jcs.auxiliary.DC.attributes.MaxKeySize=1000
I wrote 2000 items in cache, but I am able to get only 1000 items back.
What I am doing wrong ? I want to use this disk caching for items [ nearabout 50 lac items]
