    63In addition to the well known correlations, such as analysis of objects close to other objects, we will likely need to support a more general usecase: correlating any two attributes. Example: within some selected sample of objects (based say on color redshift and magnitude ranges), is there a correlation between two attributes (for example shape and surface brightness). It is expected no more than ~1-2 billion objects will need to be correlated per query, pairs of attributes at a time [per Tony].
