[jira] [Created] (ARROW-6381) [C++] BufferOutputStream::Write is slow for many small writes

Wes McKinney created ARROW-6381:
-----------------------------------

             Summary: [C++] BufferOutputStream::Write is slow for many small writes
                 Key: ARROW-6381
                 URL: https://issues.apache.org/jira/browse/ARROW-6381
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
             Fix For: 0.15.0


{{Write}} calls into {{BufferOutputStream::Reserve}} which does a surprising amount of work. I suggest streamlining the implementation and adding benchmarks for the many-small-writes case
