org.apache.hadoop.hbase.regionserver.TimeRangeTracker
Stores the minimum and maximum timestamp values (both are inclusive). Can be used to find if any given time range overlaps with its time range MemStores use this class to track its minimum and maximum timestamps. When writing StoreFiles, this information is stored in meta blocks and used at read time to match against the required TimeRange.
