asking for some help about impala-udaf

[程亚楠 <ch...@foxmail.com>]

Hello Everyone:
When I use c++ to develop my own Impala-UDAFs，how can I do to make my own Impala-UDAFs support the OVER analytic function
such as:
select myudaf(column1,column2) over(partition by column1 order by column2) from mytable;


Thank you for taking the time to read my letter!
