In Titan graph Db difference UniquenessConsistence.LOCK vs UniquenessConsistence.NO_LOCK

I am using titan for my app. What does UniquenessConsistence.LOCK mean?. Does it mean Isolation level Serializable?

What is the performance difference between UniquenessConsistence.LOCK and UniquenessConsistence.NO_LOCK?

I cannot seem to find it anywhere in Titan Documentation.

From the Titan docs:

When the underlying storage backend supports transactional isolation, titan will delegate consistency checks and locks to the storage backend. To avoid such inconsistencies on eventually consistent backends, Titan can acquire locks and will do so by default. Acquiring locks, however, can be very expensive. In cases where concurrent modifications can be excluded or blind overwrites are acceptable one may alter this default behavior.
