Hi Apoorv, Well it’s difficult to say which one is absolutely better over the other. But yes, generally Hibernate is considered to be more optimized for Persistence/Retrieval on average for large number of entities. Hibernate also offers more utility methods which at times simplifies the extra code you would have to write in OpenJPA. But I have used OpenJPA for a long enough time, and once you get beyond learning the functionalities you realize that it’s easier to deal with a minimal set of annotations in OpenJPA; whereas Hibernate has some extra wrapper annotations.
An important consideration is compatibility – OpenJPA annotations are certain to work with most JPA implementations, but not vice-versa. This plays a big role when you want to switch your JPA implementations (generally does not happen). Having said that, Hibernate has way more documentation and helpful sources online – if you’re facing any issues, etc. Thanks and Regards, Gourav Shenoy From: Apoorv Palkar <[email protected]> Reply-To: "[email protected]" <[email protected]> Date: Monday, July 31, 2017 at 10:03 AM To: "[email protected]" <[email protected]> Subject: Implementation of JPA Dear Dev, I'm currently developing the code for the registry to be used for the monitoring system in Airavata. I'm looking at the pros/cons of each JPA implementation and was wondering if anyone has any recommendations. I'm choosing between Hibernate, OpenJPA, and EclipseLink. I understand Hibernate is the most mature, widely used technology. I was trying to determine Hibernate's cons. Does anybody have previous knowledge about Hibernate ? My use case for the database(most likely MySQL DB) is to read/write/store data about experiment ID, name, and statuses. Thanks, A. Palkar --shoutout marcus
