Is there a way to like I'm adding @ManyToMany in my entity and trying to pull the 2000 record and around 50 association of each record. This is taking too much time as it's hitting single query every time to bring association
Is there a way we can improve performance?

thanks you so much for this video's sir, these tips and tricks are life saving for new learners like me :) i have once question do we still use this utility method when using spring data JPA with hibernate ?

just watched your video and wanted to run your example using CascadeType.REMOVE. I cannot reproduce the deletion of all books. Only the book written by Author1 gets deleted (Book1) when deleting Author1. Did Hibernate improve by not deleting all associated entities which are also referenced by other entities?

Could you make a video on proper use of junction table classes instead of an @ManyToMany annotation? I often see myself needing an additional column and I also feel like it makes my model easier to understand when I use junction table classes instead of @ManyToMany annotations

Hi Sir,

Just wanted to confirm, can we use generate property inside an @Embedable class?
