UUIDs
Explore the use of UUIDs in PostgreSQL as 128-bit synthetic keys and understand their advantages over sequences in distributed computing. This lesson helps learners grasp why UUIDs reduce collision risks and avoid single points of failure, improving data model reliability.

Anti-pattern
The PostgreSQL data type UUID allows for 128-bit synthetic keys rather than
32 bits with serial or 64 bits with bigserial.
Sequences
The serial family of data types is built on a sequence with a standard defined ...
