Subject [jira] [Commented] (ARROW-664) Make C++ Arrow serialization deterministic
Date Mon, 20 Mar 2017 02:41:41 GMT


Philipp Moritz commented on ARROW-664:

Thanks [~wesmckinn], I created a PR

I made zero-initialization the default (it also seems to be the default for the other builders),

written to IPC memory. The goal of this issue is to identify these cases and set the memory
to zero.
