Subject UDAF vs built in function
Date Sun, 11 Aug 2013 11:23:16 GMT

Before the advent of windowing and analytical functions in 0.11, we depend on UDAF for achieving
the desired analytical functionality in 0.8,
So, I would like to replace the UDAF with the available windowing and analytic function as
part of 0.11 upgrade .
Is there any best practices while choosing whether UDAF or built in functions? Will there
be any performance gain in this?
Please let me know your views
