[jira] [Created] (SPARK-9425) Support DecimalType in UnsafeRow

Davies Liu created SPARK-9425:
---------------------------------

             Summary: Support DecimalType in UnsafeRow
                 Key: SPARK-9425
                 URL: https://issues.apache.org/jira/browse/SPARK-9425
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Davies Liu
            Assignee: Davies Liu
            Priority: Blocker


The DecimalType has a precision up to 38 digits, so it's possible to serialize a Decimal as bounded byte array.

We could have a fast path for DecimalType with precision under 18 digits, which could fit in a single long.
