d8efc3b155 DS-MRR improvements: address review feedback for R3 version of the patch 2010-10-26 15:35:13 +04:00
Igor Babaev
79087c9e07 Ported the fix for bug #57024 (a performance issue for outer joins). 
Employed the same kind of optimization as in the fix for the cases
when join buffer is used.
The optimization performs early evaluation of the conditions from 
on expression with table references to only outer tables of
an outer join.
