    • getExecutionCount

      public long getExecutionCount()
      queries executed to the DB
      Specified by:

    • getCachePutCount

      public long getCachePutCount()
      Description copied from interface: QueryStatistics
      The number of cache puts for this query
      Specified by:
      getCachePutCount in interface QueryStatistics

    • getCacheMissCount

      public long getCacheMissCount()
      Description copied from interface: QueryStatistics
      The number of cache misses for this query

    • getExecutionRowCount

      public long getExecutionRowCount()
      Number of lines returned by all the executions of this query (from DB) For now, Query.stream()} and Query.scroll() do not fill this statistic
      Specified by:
      getExecutionRowCount in interface QueryStatistics
