Persist vs. Save in Hibernate: Understanding the Key Distinctions

In the realm of object-relational mapping (ORM) using Hibernate, understanding the difference between persist() and save() can play a crucial role in managing data persistence effectively.

Persist

The persist() operation in Hibernate is utilized to transform a transient object into a persistent one, allowing it to be managed by the persistence context. Unlike save(), persist() does not guarantee immediate assignment of an identifier to the entity. Instead, this assignment may occur during the flushing process, making it particularly useful in long-running sessions or extended persistence contexts. Additionally, persist() guarantees that INSERT statements are not executed outside of transaction boundaries, ensuring data integrity.

Save

In contrast to persist(), save() operates slightly differently. It persists the entity by returning the identifier associated with it. For certain identifier generators, such as "identity," executing an INSERT statement is immediately required. This action is not dependent on the existence of a transaction, potentially leading to complications in long-running conversations and extended persistence contexts.

In summary, persist() is employed to make transient objects persistent while save() handles both persistence and identifier generation. Persist() offers benefits in long-running contexts and transaction boundary considerations, while save() provides immediate identifier assignment and potential INSERT execution even outside of transactions.
