---------------------------------
Summary: C++: Add method to shrink PoolBuffer using realloc
Key: ARROW-360
URL: https://issues.apache.org/jira/browse/ARROW-360
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Uwe L. Korn
Assignee: Uwe L. Korn
In the case where we have optimistically allocated a large PoolBuffer, we could
shrink it later again using a call to {{realloc}}. This should free the
exceeding memory but avoids an actual {{memcpy}}.
