getCacheHitCount

public long getCacheHitCount()

Queries retrieved successfully from the cache

Specified by:

getCacheHitCount in interface QueryStatistics

getCachePutCount

public long getCachePutCount()

Specified by:

Specified by:

getExecutionRowCount in interface QueryStatistics

Returns:

The number of rows cumulatively returned by the given query; iterate and scroll queries do not effect this total as their number of returned rows is not known at execution time.
