correct. Therefore, as a best practice, it is not recommended to enable pattern generation in a production environment by manually maintaining the table mechanism. To disable mode generation, configure the configuration file Persistence.xml as follows:The generation strategy for the Generator table primary key is the generator table, which is uncommon and is typically used for legacy databases using JPA.
