Subject [jira] [Created] (KYLIN-2437) collect number of bytes scanned to query metrics
Date Wed, 08 Feb 2017 09:24:41 GMT
Dayue Gao created KYLIN-2437:
--------------------------------

             Summary: collect number of bytes scanned to query metrics
                 Key: KYLIN-2437
                 URL: https://issues.apache.org/jira/browse/KYLIN-2437
             Project: Kylin
          Issue Type: Improvement
          Components: Storage - HBase
    Affects Versions: v1.6.0
            Reporter: Dayue Gao
            Assignee: Dayue Gao


Besides scanned row count, it's useful to know how many bytes are scanned from HBase to fulfil
a query. It is perhaps a better indicator than row count that shows how much pressure a query
puts on HBase.
