Subject [jira] [Created] (KYLIN-3586) Boxing/unboxing to parse a primitive is suboptimal
Date Sun, 23 Sep 2018 20:35:00 GMT
Ted Yu created KYLIN-3586:
-----------------------------

             Summary: Boxing/unboxing to parse a primitive is suboptimal
                 Key: KYLIN-3586
                 URL: https://issues.apache.org/jira/browse/KYLIN-3586
             Project: Kylin
          Issue Type: Bug
            Reporter: Ted Yu


An example is from HBaseLookupRowEncoder:
{code}
            int valIdx = Integer.valueOf(Bytes.toString(qualifier));
{code}
valueOf returns an Integer object which would be unboxed and assigned to valIdx.

Integer.parseInt() should be used instead.
