---------------------------------------
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.
