Subject [jira] [Created] (DRILL-1526) Improve cast functions that cast varchar to numeric type
Date Fri, 10 Oct 2014 20:31:33 GMT

----------------------------------

             Summary: Improve cast functions that cast varchar to numeric type
                 Key: DRILL-1526
                 URL: https://issues.apache.org/jira/browse/DRILL-1526
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Mehant Baid
             Fix For: 0.7.0


The cast function implementation to go from varchar to int/bigint is relatively large and
every time we use this function, we add this logic to our run time generated class and JVM
has to optimize the same logic multiple times. Instead it would be useful to have a utility
method that contains the casting logic, which will be called in the runtime generated code
that the JVM will need to optimize only once.
