Hi Marton. Yes, this performs a batch get which retrieves all entities in
parallel, which should be much more efficient than fetching sequentially
with getObjectById.

Hi Max,
I am surprised that this actually works. :)
I could not find the documentation describing this feature. Do you
know how is this implemented? Is it more efficient than just calling
getObjectByIdentity N (=listOfKeys.size()) times?
Thanks,
Marton

Bulat,
Does that work for you? If so, could you please post an example?
Thanks,

Use one of the getObjectsById methods - just pass a collection of IDs
as a parameter.

Please try not to double-post in the future.

You can do the equivalent of a low level batch get with jdoql:
Query q = pm.newQuery("select from " + Flight.class.getName() + " where
id == :ids");
@SuppressWarnings("unchecked")
List flights = (List) q.execute(listOfKeys);
Hope this helps,
Max
