> In addition to our traditional memory estimates (based on exact or worst-case dimensions
and sparsity), operator selection also performs a check for valid integer dimensions and maximum
dense size. However, this dimension/size check does not take worst-case estimates into account.
Therefore, we currently compile unnecessary distributed operations for operations that produce
ultra-sparse outputs without exactly known sparsity such as rexpand.
