Wes McKinney created ARROW-1712:
-----------------------------------
Summary: [C++] Add method to BinaryBuilder to reserve space for
value data
Key: ARROW-1712
URL: https://issues.apache.org/jira/browse/ARROW-1712
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
The {{Resize}} and {{Reserve}} methods only reserve space for the value
offsets. When building binary/string arrays with a known size (or some
reasonable estimate), it would be more efficient to reserve once at the
beginning to prevent internal reallocations
