### `lmdb_map_size`

This parameters can be used to set the map size used by LMDB,

The value of this parameter is the maximum size the metadata database can take.

This value is not bound by the physical RAM size of the machine running Garage.

If not specified, it defaults to 1GiB on 32-bit machines and 1TiB on 64-bit machines.
