David Li reopened ARROW-11475:
------------------------------
Reverted in [https://github.com/apache/arrow/pull/10024] as we found
performance regressions and a bug in mimalloc
([https://github.com/microsoft/mimalloc/issues/363]).
> [C++] Upgrade mimalloc
> ----------------------
>
> Key: ARROW-11475
> URL: https://issues.apache.org/jira/browse/ARROW-11475
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Neal Richardson
> Assignee: Antoine Pitrou
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0
>
> Time Spent: 5h
> Remaining Estimate: 0h
>
> I tried this in ARROW-11350 but ran into an issue
> (https://github.com/microsoft/mimalloc/issues/353). That has since been
> resolved and we could apply a patch to bring it in. Or we can wait for it to
> get into a proper release.
> There is also now a 1.7 release, which claims to work on the Apple M1, as
> well as a 2.0 version, which claims better performance.
