allocator from jemalloc to mimalloc
Neal Richardson created ARROW-12316:
---------------------------------------
Summary: [C++] Switch default memory allocator from jemalloc to mimalloc
Key: ARROW-12316
URL: https://issues.apache.org/jira/browse/ARROW-12316
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Neal Richardson
Fix For: 4.0.0
Benchmarking shows that mimalloc seems to be faster on real workflows (at least on macOS, still collecting data on Ubuntu). We could switch the default memory pool cases so that mimalloc is preferred.
