-----------------------------------
Resolution: Won't Fix
> In TypedAggregateExpression update method we call encoder.shift many times
> --------------------------------------------------------------------------
>
> Key: SPARK-14627
> URL: https://issues.apache.org/jira/browse/SPARK-14627
> Project: Spark
> Issue Type: Improvement
> Reporter: Liang-Chi Hsieh
> Priority: Minor
>
> Every time we call TypedAggregateExpression.update method, we call encoder's
> shift method. As shift method will copy encoder and underlying
> BoundReference, we should prepare the shifted encoder in advance, instead of
> calling shift method every time.
> BTW, we can also improve encoder's shift method to return itself when shift
> delta is zero.
