Doc Type: Bug Fix
Doc Text:
Users are finding that large sorts are inefficient. When the memory space needed for a sort is estimated to be above 2 GB, the expression used will overflow. This causes the batch size to be used as the intermediate sort buffer size, which for any high row count will lead to many passes.
