Chunyang Wen commented on ORC-40:
---------------------------------
Most of the APIs have been implemented using C++. But in order to reduce memory
leak problem, I use std::shared_ptr which is supported in C++11.
Whether C++ sources will only be compiled in compilers which support at C++11
(with option -std=c++11)?
If so, I will use std::shared_ptr, otherwise I am considering boost::shared_ptr
from boost (Actually I think shared_ptr comes from tr1 which originates from
boost)
> C++ Reader does not support predicate pushdown.
