Thanks for the analysis. Interestingly when we first released our low latency s3-compatible storage (1M IOPS, p99 ~5ms)[1], a lot of people asking the same questions why we tried to bring file system semantics (atomic object/folder rename) to s3. We also got some feedback from people who really need FS sematics, and added POSIX FS support then. aws S3FS is using normal FUSE interface, which would be super heavy due to inherent overhead of copying data back and forth between user space and kernel space, that is the initial concern when we tried to add the POSIX support for the original object storage design. Fortunately, we have found and open-sourced a perfect solution [2]: using FUSE_OVER_IO_URING + FUSE_PASSTHROUGH, we can maintain the same high-performance archtecture design of our original object storage. We'd like to come out a new blog post explain more details and reveal our performance numbers if anyone is interested with this.
