Functions ¶
Types ¶
type Service ¶
type Service struct {
// contains filtered or unexported fields
}
Service is a high-level service for managing file content and its metadata. It orchestrates interactions between the metadata store (metaStore) and the blob store (blobStore). It is stateless and operates on content IDs (metaID), not paths.
func NewService ¶
func NewService(metaStore metaiface.Store, basePath string, assembler contentiface.Assembler, chunkSize int64) (*Service, error)
NewService creates a new Service instance.
func (*Service) Create ¶
Create reads content from a reader, stores it (either embedded or as sharded blobs), persists the metadata, and returns the unique metadata ID. It optimizes based on whether the input `size` is known.
func (*Service) Delete ¶
Delete orchestrates the deletion of file content (blobs) and the metadata record.
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store implements the metaiface.Store interface using the local filesystem. It relies on a ShardedStorage layout to manage the physical files.
func (*Store) Create ¶
Create serializes the FileMeta and stores it using a pre-determined, content-derived ID. The caller is responsible for generating the correct ID.
func (*Store) CurrentVersion ¶
CurrentVersion returns the version number used for writing new metadata. The system maintains backward compatibility for reading older, supported versions.
