Description

Feature description

Today UUID is supported by Micronaut Data as auto generated primary keys. It would be great to also have support for CUIDs.

"CUID is a more modern approach to generating unique identifiers, designed to be more collision-resistant than UUIDs. CUIDs are shorter, making them more efficient to use in databases and easier to handle in URLs. They are also sequential to a degree, which can help with database indexing performance."

There is no CUID2 implementation i Java SDK so Micronaut would have to supply its own.

Research direction

Start by tracing existing UUID handling for @AutoPopulated @Id and checking the Java SDK's identifier-generation APIs. Confirm the CUID representation and generation semantics, then add focused coverage showing CUID primary keys are generated and persisted.
