func (*SnapshotLoader) CleanupSinker 

func (l *SnapshotLoader) CleanupSinker(tables abstract.TableMap) error

CleanupSinker cleans up the sinker when non-incremental transfer is activated.

This method changes the sinker database' contents, thus it should be called only after the checks on source (that ensure a transfer is possible) are completed.
