Does anyone explain what does the following parameters mean in SOLR cache
statistics?
*name*: queryResultCache
*class*: org.apache.solr.search.LRUCache
*version*: 1.0
*description*: LRU Cache(maxSize=512, initialSize=512)
*stats*: lookups : 98
*hits *: 59
*hitratio *: 0.60
*inserts *: 41
*evictions *: 0
*size *: 41
*warmupTime *: 0
*cumulative_lookups *: 98
*cumulative_hits *: 59
*cumulative_hitratio *: 0.60
*cumulative_inserts *: 39
*cumulative_evictions *: 0
AND also this
*name*: fieldValueCache
*class*: org.apache.solr.search.FastLRUCache
*version*: 1.0
*description*: Concurrent LRU Cache(maxSize=10000, initialSize=10,
minSize=9000, acceptableSize=9500, cleanupThread=false)
*stats*: *lookups *: 8
*hits *: 4
*hitratio *: 0.50
*inserts *: 2
*evictions *: 0
*size *: 2
*warmupTime *: 0
*cumulative_lookups *: 8
*cumulative_hits *: 4
*cumulative_hitratio *: 0.50
*cumulative_inserts *: 2
*cumulative_evictions *: 0
*item_ABC *:
{field=ABC,memSize=340592,tindexSize=1192,time=1360,phase1=1344,nTerms=7373,bigTerms=1,termInstances=11513,uses=4}
*item_BCD *:
{field=BCD,memSize=341248,tindexSize=1952,time=1688,phase1=1688,nTerms=8075,bigTerms=0,termInstances=13510,uses=2}
Without understanding these terms i cannot configure server for better cache
usage. The point is searches are very slow. These stats were taken when
server was down and restarted. I just want to understand what these terms
mean actually
