Hi, I am trying to find out how exactly Kudu accesses storage. Does Kudu use mmap to access file content or does rather rely on regular open/read/seek/write?
Also, does Kudu offer any kind of consistency operations to clients, to ensure that data is persisted on-disk, or transferred to additional replica nodes? (hsync/hflush equivalent) Any explanation / pointer to the relevant source files is much appreciated. Best, Jan
