If the inner relation has an index on the attributes used in the join, then the naive nest loop join can be replaced with an index join. algorithm index_join is for each tuple r in R do for each tuple s in S in the index lookup do yield tuple <r,s>

[4]: 115 DataFrames can be concatenated together or "merged" on columns or indices in a manner similar to joins in SQL.
