Description

I've noticed that the jemalloc const configuration je_arrow_malloc_conf overrides the arrow public function jemalloc_set_decay_ms().

Is their a way to call jemalloc_set_decay_ms so that it has the right precedence ?
-> if yes, I believe this should be specified in the comments
-> if no, the function should be deprecated
