The unique column (technically 2 columns that combined are unique)
functions as a pretty typical id. Yes, I do run joins on it, but the
performance advantage of an additional index is outweighed by the
ingest performance hit due to the cardinality of the outer relation
(hash joins are typically used) and the relatively small row size.
