> If you are creating a disk-backed memory map then the OS needs to write out the data at some point. What happens if you locate your memory mapped file inside a tmpfs such as `/dev/shm`? I don't want to map a file to memory, It will cause some data synchronize. Does pyarrow support communication inter-process(IPC) without mapping a file?Just like multiprocessing. sharedctypes only use sharing memory to do it. -- This is an automated message from the Apache Git Service.
