> a concrete implementation of the [specs-storage](https://github.com/filecoin-project/specs-storage) interface
|
|
|
|
The sector-storage project provides a implementation-nonspecific reference implementation of the [specs-storage](https://github.com/filecoin-project/specs-storage) interface.

|
## Architecture
|
|
|
|
|
|
|
|
### `Manager`
|
|
|
|
Manages is the top-level piece of the storage system gluing all the other pieces
|
|
together. It also implements scheduling logic.
|
|
|
|
### `package stores`
|
|
|
|
This package implements the sector storage subsystem. Fundamentally the storage
|
|
is divided into `path`s, each path has it's UUID, and stores a set of sector
|
|
'files'. There are currently 3 types of sector files - `unsealed`, `sealed`,
|
|
and `cache`.
|
|
|
|
Paths can be shared between nodes by sharing the underlying filesystem.
|
|
|
|
### `stores.Local`
|
|
|
|
The Local store implements SectorProvider for paths mounted in the local
|
|
filesystem. Paths can be shared between nodes, and support shared filesystems
|
|
such as NFS.
|
|
|
|
stores.Local implements all native filesystem-related operations
|
|
|
|
### `stores.Remote`
|
|
|
|
The Remote store extends Local store, handles fetching sector files into a local
|
|
store if needed, and handles removing sectors from non-local stores.
|
|
|
|
### `stores.Index`
|
|
|
|
The Index is a singleton holding metadata about storage paths, and a mapping of
|
|
sector files to paths
|
|
|
|
### `LocalWorker`
|
|
|
|
LocalWorker implements the Worker interface with ffiwrapper.Sealer and a
|
|
store.Store instance
