Re: [eclipselink-users] Configuring batch reading in JPA?

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Laird,

  At the moment, the way to configure batch reading on a mapping is through a 
DescriptorCustomizer as described in a link accessible from the one you have 
provided.

http://wiki.eclipse.org/Configuring_a_Relational_Mapping_%28ELUG%29#How_to_Configure_Batch_Reading_Using_Java

  Adding batching as an annotation and orm.xml element would be a good idea. 
Please feel free to add an enhancement request.
