UUIDV7 IN 33 LANGUAGES
Summary from the TLDR Web Dev newsletter
UUIDv7 is a 128-bit unique identifier designed to be time-sortable with 1 ms precision, making it suitable for use in databases, including distributed systems. Unlike its predecessor UUIDv4, UUIDv7 integrates both timestamp and random components, ensuring sequential ordering based on time. This makes UUIDv7 a great option for generating unique identifiers for database records that require precise chronological ordering.
