Types

type Sync

type Sync struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Sync provides methods for syncing records to heavy storage.

func NewSync

func NewSync(db *storage.DB) *Sync

NewSync creates new Sync instance.

func (*Sync) Reset

func (s *Sync) Reset(ctx context.Context, jetID core.RecordID, pn core.PulseNumber) error

Reset resets sync for provided pulse.

func (*Sync) Start

func (s *Sync) Start(ctx context.Context, jetID core.RecordID, pn core.PulseNumber) error

Start try to start heavy sync for provided pulse.

func (*Sync) Stop

func (s *Sync) Stop(ctx context.Context, jetID core.RecordID, pn core.PulseNumber) error

Stop successfully stops replication for specified pulse.

TODO: call Stop if range sync too long

func (*Sync) Store

func (s *Sync) Store(ctx context.Context, jetID core.RecordID, pn core.PulseNumber, kvs []core.KV) error

Store stores recieved key/value pairs at heavy storage.

TODO: check actual jet and pulse in keys
