Do you mean for the same query, even if the memory configured for LRU is big enough, some of the cached entries for index still get purged? --yes i think it is.
However, since your query is purely count-star without any conditions, I suppose the query may not use the index are all, which means the LRU cache may donot work for your query. --but by logs we can see the carbonindexmerge file load to LRUCache. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
