Hi,
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 Thanks, Pandeesh — Sent from Mailbox for iPad
