func (*NopWAL) Log ¶

func (w *NopWAL) Log(_ uint64, _ *walpb.Record) error

func (*NopWAL) LogRecord ¶

func (w *NopWAL) LogRecord(_ uint64, _ string, _ arrow.Record) error

func (*NopWAL) Replay ¶

func (w *NopWAL) Replay(_ uint64, _ ReplayHandlerFunc) error

func (*NopWAL) Reset ¶

func (w *NopWAL) Reset(_ uint64) error

func (*NopWAL) Truncate ¶

func (w *NopWAL) Truncate(_ uint64) error

type ReplayHandlerFunc ¶

type ReplayHandlerFunc func(tx uint64, record *walpb.Record) error

type TestingOption ¶

type TestingOption func(*FileWAL)

func WithTestingLogStoreWrapper ¶

func WithTestingLogStoreWrapper(newLogStoreWrapper func(wal.LogStore) wal.LogStore) TestingOption

func WithTestingLoopTicker ¶

func WithTestingLoopTicker(t Ticker) TestingOption
