To be clear, we have recently switched the default to mimalloc, so jemalloc shouldn't be involved unless users explicitly ask for it. As for which allocator is better, there is no simple, clear-cut answer, because it depends on the workload, the platform and the metrics you care about (is the user more sensitive to memory footprint or execution time?). Sometimes people are unhappy about the behavior of the default allocator on their workload and it turns out they can work around their issues simply by changing the allocator, which is rather nice. -- This is an automated message from the Apache Git Service.
