The following hash index is distributed explicitly on l_partkey and stored explicitly in row-hash order on l_partkey:
CREATE HASH INDEX line_hidx_2 (l_partkey) ON lineitem BY (l_partkey) ORDER BY HASH (l_partkey);
This creates an index that is equivalent in structure to the following join index.
CREATE JOIN INDEX line_jidx_2 AS SELECT (l_partkey), (l_orderkey, lineitem.ROWID) FROM lineitem PRIMARY INDEX (l_partkey);
