> Based on research done for ARROW-1282, when using jemalloc along with other allocators, it is recommended to build jemalloc with a prefix to be used on all calls (so as not to confuse those calls with that of other allocators). See https://github.com/jemalloc/jemalloc/wiki/Getting-Started for more info.
