Architecture

high-level 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 paths, 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
