I am setting batch-size=30 on my collections, but NH is batching in groups of 10. Is there a maximum limit to the batch size? If so, can I increase it?

Thanks

There is no such limit that I am aware of, maybe you have only 10 uninitalized collections

Interesting. I think I have found a bug in NH. When using a batch-size on a child collection when the parent has a composite primary id, NH is not correctly counting the batch size. It is counting the number of parameters in the SQL command rather than the number of objects.

So if I have a composite id with 2 fields, the batch-size used actually half what it should be since there are twice as many parameters in the select statement.

Not sure if I am explaining this very well.

Can you create a simple test case showing the problem?
