How To Generate Sequences Of Identifiers Via Hibernate hi/lo Algorithm

Note: If systems external to your application need to insert rows in your tables then don't rely on hi/lo algorithm since, in such cases, it may cause errors resulted from generating duplicated identifiers. Rely on pooled or pooled-lo algorithms (optimizations of hi/lo).

Description: This is a Spring Boot example of using the hi/lo algorithm for generating 1000 identifiers in 10 database roundtrips for batching 1000 inserts in batches of 30.

Key points:

• use the SEQUENCE generator type (e.g., in PostgreSQL)
• configure the hi/lo algorithm as in Author.java entity

Output example:
