"Can we always mark yes for Kundera if we list out all benefit of JPA 2.0 promised? If we can not, why Kundera is declared to be JPA compatible?"
<Vivek>Yes, you can mark it. It is not a 100% JPA compatible(Kundera never claimed it) but it provides all the features in JPA way. Not introducing any new annotation/class specifically other than JPA spec. </Vivek> Kundera is JPA compatible. -Vivek ________________________________________ From: yiyu jia [[email protected]] Sent: 09 November 2012 20:41 To: [email protected] Subject: Re: Kundera 2.2 released Thanks for info. I skim over the FAQ of Kundera. I found this: *Q:* OK...OK...I understand simplicity, ease of use and all that stuff, but what about flexibility and power that I am accustomed to while using that plain vanilla low level library like thrift? *A:* We understand JPA was built for relational databases and may not always provide you ways to perform functions (many times with certain tweaks) that are NoSQL specific. That's the reason we introduced data-store specific configuration in Kundera-2.0.7. For more on this, refer to So, it looks like my suspection is reasonable and others asked same question before already. Can we always mark yes for Kundera if we list out all benefit of JPA 2.0 promised? If we can not, why Kundera is declared to be JPA compatible?
