> There is potential for incorrect unary aggregates over compressed matrices in the presence of a mix of OLE/RLE groups with existing UC group. Since we directly invoke uncompressed operations, the UC group computation resets the partial aggregates computed over predecessor groups. 
> The fix should invoke uncompressed operations first before processing OLE and RLE groups.
