> In Python, there is a [{{log_memory_allocations}} function|https://github.com/wesm/arrow/blob/33111644be84f84ce4601889fee06c6d17f05279/python/pyarrow/memory.pxi#L63] to change to use the LoggingMemoryPool. It would be nice to be able to do this in C++ and one very convenient way would be through an environment variable, since we already support {{ARROW_DEFAULT_MEMORY_POOL}}. Should probably be named something like {{ARROW_LOG_MEMORY_ALLOCATIONS}}.
