- // `SimpleFileSystem` is a low-level filesystem designed to communicate
with FUSE APIs.
- // It manages file and directory relationships, as well as file mappings.
- // It delegates file operations to the PathFileSystem
- //
- // `FileSystemLog` is a decorator that adds extra debug logging
functionality to file system APIs.
- // Similar implementations include permissions, caching, and metrics.
- //
- // `GravitinoComposeFileSystem` is a composite file system that can
combine multiple `GravitinoFilesetFileSystem`.
- // It use the part of catalog and schema of fileset path to a find actual
GravitinoFilesetFileSystem. delegate the operation to the real storage.
- // If the user only mounts a fileset, this layer is not present. There
will only be one below layer.
- //
- // `GravitinoFilesetFileSystem` is a file system that can access a
fileset.It translates the fileset path to the real storage path.
- // and delegate the operation to the real storage.
- //
- // `OpenDALFileSystem` is a file system that use the OpenDAL to access
real storage.
- // it can assess the S3, HDFS, gcs, azblob and other storage.
- //
- // `S3FileSystem` is a file system that use `OpenDALFileSystem` to access
S3 storage.
- //
- // `HDFSFileSystem` is a file system that use `OpenDALFileSystem` to
access HDFS storage.
- //
- // `NasFileSystem` is a filesystem that uses a locally accessible path
mounted by NAS tools, such as JuiceFS.
- //
- // `JuiceFileSystem` is a file that use `NasFileSystem` to access JuiceFS
storage.
- //
- // `XXXFileSystem is a filesystem that allows you to implement file access
through your own extensions.

Review Comment:
The mount point does't unmounted, users need to umount the directory
manually.
Typical FUSE programs do not run in the foreground, and exiting with Ctrl+C
is not the standard practice.
This mode is used for testing and debugging.
