# The fuse section describes settings for the FUSE file system. This file system
# is used as a thin layer between the SQLite client in your application and the
# storage on disk. It intercepts disk writes to determine transaction boundaries
# so that those transactions can be saved and shipped to replicas.

# The data section describes settings for the internal LiteFS storage. We'll
# mount a volume to the data directory so it can be persisted across restarts.
# However, this data should not be accessed directly by the user application.
