-------------------------------------
Summary: [C++] Add OutputStream::Write() variant taking an owned
buffer
Key: ARROW-6527
URL: https://issues.apache.org/jira/browse/ARROW-6527
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Antoine Pitrou
When Write() takes an arbitrary data pointer and needs to buffer it, it is
mandatory to copy the data because the pointer may go stale, or the data may be
overwritten.
Buf if the user has an immutable Buffer, then it should be enough to store the
Buffer as necessary, without doing a memory copy. We could add a special
Write() variant for that.
