# 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.
fuse:
  dir: "/litefs"

# 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.
data:
  dir: "/var/lib/litefs"

# This flag ensure that LiteFS continues to run if there is an issue on starup.
# It makes it easy to ssh in and debug any issues you might be having rather
# than continually restarting on initialization failure.

# This section defines settings for the option HTTP proxy.
# This proxy can handle primary forwarding & replica consistency
# for applications that use a single SQLite database.

# This section defines a list of commands to run after LiteFS has connected
# and sync'd with the cluster. You can run multiple commands but LiteFS expects
# the last command to be long-running (e.g. an application server). When the
# last command exits, LiteFS is shut down.

# The lease section specifies how the cluster will be managed. We're using the
# "consul" lease type so that our application can dynamically change the primary.
#
# These environment variables will be available in your Fly.io application.
