Class CacheStatistics

java.lang.Object
org.apache.sysds.runtime.controlprogram.caching.CacheStatistics
public class CacheStatistics extends Object
This singleton provides basic caching statistics in CP. 1) Hit statistics for caching (mem, fs, hdfs, total) NOTE: In order to provide accurate statistics in multi-threaded synchronized increments are required. Since those functions are called potentially very often, we use atomic increments (compare and swap) instead of heavy-weight 'synchronized' methods.
