[jira] [Created] (ARROW-12316) [C++] Switch default memory 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.
