Change subject: KUDU-2162 Expose stats about scan filters ...................................................................... KUDU-2162 Expose stats about scan filters This patch adds a couple of resource metrics to scanners. - bytes read, from disk or cache - elapsed time processing the scan request, in nanoseconds These metrics can be used to roughly compare the amount of work done by scan operations, and could be useful for runtime optimizations in query planners like Impala or Spark.
