The "data" setting of ext filesystems isn't replacement for fsync().
- Dylan16807 3y agoIt's not a replacement but it can give you some guarantees. Also fsync is a terrible API that should be replaced, but that's mostly a different topic.
- the8472 3y agoAt least on linux you can use io_uring to make fsync asynchronous. And you can initiate some preparatory flushing with sync_file_range and only do the final commit with fsync to cut down the latency.
