pitrou opened a new issue, #44976: URL: https://github.com/apache/arrow/issues/44976
### Describe the enhancement requested 1. Since mimalloc has [become the default allocator](GH-43254) instead of jemalloc, mimalloc should be enabled by default, and jemalloc disabled by default. 2. compute-specific files should only be compiled when compute is enabled. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
