> Batch Update support needed for OpenJPA performance
> ---------------------------------------------------
>
> Key: OPENJPA-180
> URL: https://issues.apache.org/jira/browse/OPENJPA-180
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 0.9.0, 0.9.6, 0.9.7, 1.0.0, 1.1.0
> Environment: All
> Reporter: John Stecher
>
> After doing some more performance testing on OpenJPA using a variety of
> primitive benchmarks I have noticed that it lags competitors significantly in
> performance in scenarios that stress multiple updates inside of a single
> transaction. Obviously almost every application server out there today
> overcomes this by implementing some sort of batch update feature and I would
> almost consider it a bug that OpenJPA does not have this support as it
> appears that Hibernate and Toplink both do as do most J2EE vendors CMP 2.X
> containers.
> I would say that the ramifications of not shipping batch update support would
> be fairly huge from both a JPA performance perspective but also from the more
> costly backend database perspective where typically CPU cycles are far more
> limited than on the application server machine. Looking at most complex
> applications in the market place today and realizing almost all of them need
> this support to some degree I want this JIRA to drive that feature into
> OpenJPA. Given the fact so many legacy containers and persistence engines
> have support for it, I consider it a bug that OpenJPA does not have it
> already.
> Always open for thoughts. Just started looking at this so I am not sure if
> it has been brought up in the past but does anyone have ideas or
> implementation prototypes that we could work together to build?
