This looks like an ordinary hash join, not a star transformation. Is there any way you could use bitmap indexes to achieve the star transformation, which really the only way that will make such a huge fact/detail query run reasonably fast. If only there was some kind of a physical contraption that could use Bloom filter to quickly eliminate unnecessary blocks from the fact table during the full table scan. And if it use some kind of compression that would lower the number of blocks to be read, that would be an additional boost.
