If you plan to store UUID values in a Primary Key column, then you are better off using a TSID (time-sorted unique identifier).
One such implementation is offered by the Hypersistence TSID OSS library, which provides a 64-bit TSID that’s made of two parts:
a 42-bit time component a 22-bit random component
The random component has two parts:
a node identifier (0 to 20 bits) a counter (2 to 22 bits)
The node identifier can be provided by the tsid.node system property when bootstrapping the application: -Dtsid.node="12"
