This is the default mode on macOS. +* `batch` enables a mode that uses writeout-only flushes to stage multiple + updates in the disk writeback cache and then does a single full fsync of + a dummy file to trigger the disk cache flush at the end of the operation. ++ +Currently `batch` mode only applies to loose-object files.
