One thing people forget about in all the excitement over HLL's is how effectiveness of compressed bitsets, which aren't lossy and so yield precise answers. They exploit the same "90% of them will be zero" phenomenon for space and execution efficiency, but are much more flexible... in exchange for consuming more memory and being slower than HLL's. |
