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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
