type SetOptions ¶

func WithDestroy ¶
func WithDestroy() SetOptions
WithDestroy returns a closure that sets an option so that instead of creating a tombstone, the data is permanently deleted from the database, meaning that a subsequent Put will restart the versioning. Use Destroy with care in a distributed system, if you destroy a key in an anti-entropy environment it will simply be repaired by the system to the latest version before the Delete.
