[Wonder-disc] ERXFetchSpecificationBatchIterator

[Camille T. <cam...@od...>]

Hello all !

I am trying to use ERXFetchSpecificationBatchIterator.
It seems to be a GREAT tool, but I have some problems with memory 
management.
I have to fetch 200k+ objects and I am running OutOfMemory(Error) 
before 56k objects.

I have taken care to create a non-validating EOEditingContext with 
undo-manager set to null every time a batch of 200 fetches is completed.

Do I have to call invalidateAllObjects on my editing-context at every 
batch loop ?
I am not doing exotic computations with fetched objects.  Some of their 
values are just written to a CSV -> Zip -> File chained stream.

If anyone has used this successfully to achieve the same thing (and 
fetch zillions of objects!) please, help me.


Best Regards,
Camille
