  2. Ok, the post is calling “JPA batch inserts (using Hibernate and Spring Data JPA)”

    Can you please give an explanation or manual how to make JPA batch inserts (using Hibernate and Spring Data JPA) ?

    Thank you.
    I agree with Adeel Ahmad and I understand what did he ask about. As far as I understand = that same question as I am.

    1. Hhhm, ok…thanks for your feedback. You need to read the articles I linked to in order to understand what problem is. Would you rather want me to repeat the solutions documented in the other articles?

  3. Hi,

    Thanks for your interesting links.

    I understand that from time to time, it’s necessary to empty the first level cache and send everything to the database:


    However since Spring Data JPA Repositories are used here, there is only a flush() method from JpaRepository exposed. Does the call to this method is strictly equivalent to the above two calls ?

    JpaRepository does not expose a clear() method. SimpleJpaRepository never ever call the clear() method of its internal JPA EntityManager.
