-----------------------------------
Summary: [C++][Python] Expose method for benchmarking tools to
release unused memory from the allocators
Key: ARROW-12584
URL: https://issues.apache.org/jira/browse/ARROW-12584
Project: Apache Arrow
Issue Type: Improvement
Components: C++, Python
Reporter: Weston Pace
A team working on Arrow benchmarks encountered a problem where the mimalloc
allocator was holding onto considerably more RAM than needed (at least 6GB and
potentially more).
Mimalloc offers the `mi_collect` non-standard API which forces mimalloc to
release unused pages to the OS. We could expose this to be called by
benchmarking tools to get consistent results and reduce the amount of RAM
needed.
