   If you don't want to install Arrow from source you can try using the environment variable `ARROW_DEFAULT_MEMORY_POOL` to switch to a different allocator:
   
   ```
   (arrow-release-5) pace@pace-desktop:~$ ARROW_DEFAULT_MEMORY_POOL=jemalloc python -c "import pyarrow; print(pyarrow.default_memory_pool().backend_name)"
   jemalloc
   (arrow-release-5) pace@pace-desktop:~$ ARROW_DEFAULT_MEMORY_POOL=system python -c "import pyarrow; print(pyarrow.default_memory_pool().backend_name)"
   system
   (arrow-release-5) pace@pace-desktop:~$ ARROW_DEFAULT_MEMORY_POOL=mimalloc python -c "import pyarrow; print(pyarrow.default_memory_pool().backend_name)"
   mimalloc
   ```
   
   I'm not sure off the top of my head what options are available in the pyarrow wheel.
   
   Also, some research suggests that there might be certain settings that can be set to get jemalloc working.  Can you share your Dockerfile so I can try and reproduce?
