Are you struggling with slow database operations in your Java applications? Hibernate batch processing might just be the game-changer you need! By optimizing how your application interacts with the database, you can drastically improve performance and scalability. Letโ€™s explore some key tips and best practices! ๐Ÿ”ฅ

If you're using ID generation strategies, avoid the identity generator. Instead, opt for strategies like sequence or pooled. This can reduce your database round trips! ๐Ÿš€
