Constants

const (
	// BoltPointerBucket is the string representing the bucket used for `PointerEntries` in BoltDB
	BoltPointerBucket = "pointers"
)

Variables

var (

	// Error general metainfo error
	Error = errs.Class("metainfo error")
)

Functions

func CreatePath

func CreatePath(projectID uuid.UUID, segmentIndex int64, bucket, path []byte) (storj.Path, error)

CreatePath will create a Segment path

func NewStore

func NewStore(logger *zap.Logger, dbURLString string) (db storage.KeyValueStore, err error)

NewStore returns database for storing pointer data

Types

type APIKeys

type APIKeys interface {
	GetByHead(ctx context.Context, head []byte) (*console.APIKeyInfo, error)
}

APIKeys is api keys store methods used by endpoint

type Config

type Config struct {
	DatabaseURL          string      `help:"the database connection string to use" releaseDefault:"postgres://" devDefault:"bolt://$CONFDIR/pointerdb.db"`
	MinRemoteSegmentSize memory.Size `default:"1240" help:"minimum remote segment size"`
	MaxInlineSegmentSize memory.Size `default:"8000" help:"maximum inline segment size"`
	Overlay              bool        `default:"true" help:"toggle flag if overlay is enabled"`
	BwExpiration         int         `default:"45"   help:"lifespan of bandwidth agreements in days"`
}

Config is a configuration struct that is everything you need to start a metainfo

type Endpoint

type Endpoint struct {
	// contains filtered or unexported fields
}

Endpoint metainfo endpoint

func NewEndpoint

func NewEndpoint(log *zap.Logger, metainfo *Service, orders *orders.Service, cache *overlay.Cache,
	apiKeys APIKeys, sdb accounting.StoragenodeAccounting,
	pdb accounting.ProjectAccounting, liveAccounting live.Service,
	maxAlphaUsage memory.Size) *Endpoint

NewEndpoint creates new metainfo endpoint instance

func (*Endpoint) Close

func (endpoint *Endpoint) Close() error

Close closes resources

func (*Endpoint) CommitSegment

func (endpoint *Endpoint) CommitSegment(ctx context.Context, req *pb.SegmentCommitRequest) (resp *pb.SegmentCommitResponse, err error)

CommitSegment commits segment metadata

func (*Endpoint) CreateSegment

func (endpoint *Endpoint) CreateSegment(ctx context.Context, req *pb.SegmentWriteRequest) (resp *pb.SegmentWriteResponse, err error)

CreateSegment will generate requested number of OrderLimit with coresponding node addresses for them

func (*Endpoint) DeleteSegment

func (endpoint *Endpoint) DeleteSegment(ctx context.Context, req *pb.SegmentDeleteRequest) (resp *pb.SegmentDeleteResponse, err error)

DeleteSegment deletes segment metadata from satellite and returns OrderLimit array to remove them from storage node

func (*Endpoint) DownloadSegment

func (endpoint *Endpoint) DownloadSegment(ctx context.Context, req *pb.SegmentDownloadRequest) (resp *pb.SegmentDownloadResponse, err error)

DownloadSegment gets Pointer incase of INLINE data or list of OrderLimit necessary to download remote data
