Brand Details

Type: Product

Description: UUIDv7 is a 128-bit universally unique identifier (UUID) that, unlike its predecessor UUIDv4, is time-sortable with millisecond precision. This time-sorting capability is achieved by encoding a Unix timestamp within the UUID itself. This makes UUIDv7 particularly beneficial as a primary key in databases, especially distributed ones, because it improves temporal locality and reduces the performance issues associated with the randomness of UUIDv4. The improved performance stems from the fact that data inserted around the same time will be clustered together in database indexes, leading to better cache hit ratios.
