pub fn get_dist_key_start_index_in_pk(
dist_key_in_pk_indices: &[usize],
) -> Option<usize>Expand description
Get distribution key start index in pk, and return None if dist_key_in_pk_indices is not empty
or continuous.
Note that dist_key_in_pk_indices may be shuffled, the start index should be the
minimum value.
