Scalable Sequence for PostgreSQL
However, PostgreSQL caches the sequences per-connection (different from Oracle that caches in the instance shared memory). Sequences can be a bottleneck in case of a storm where all have a cold cache, and here is a workaround. Note that re-connecting in PostgreSQL is expensive for many reasons and better fixt that with a connection pool that is not too dynamic (if you need this, you should have a look at FlexiPool)

Spring Boot — Power of Value Objects
Unfortunately, you cannot smoothly wrap the sequence-based IDs with value objects. There are solutions, but they are rather cumbersome.
